(S or Spacebar) - dùng để chọn hoặc transform (scale và rotate, skew click 2 lần).
- Chức năng - chọn và transform (move, rotate, scale, shear) một hoặc nhiều đối tượng.
- Thao tác
- Click 1 lần: chọn, scale
- Click 2 lần: rotate, skew
Node Tool 
(N)
- Chức năng - Thao tác với node và handle để định dạng đường path
- Thao tác
- Click và drag node và handle
- Shift-C will let you adjust the node’s handles independently of each other. (That’s if the node is set to Smooth/Symmetrical.)
- If your node already has an independent handle, Shift-C will turn your node into a Corner. When your path or object has a gradient, either within the fill or stroke, the Node tool is also capable of adjusting the gradient handles without the need to switch to the Gradient Tool.
- Click và a section between nodes to adjust the curve.
- Click và drag node và handle
Tweak Tool 
(W) The tweak tool actually has quite a few tricks. You can push and pull paths and objects, shrink, roughen, shift the object’s color, and blur the object. This same tool allows you to manipulate groups of objects, similar to the symbol manipulation tools in Adobe Illustrator.
The Tweak Objects tool allows you to make compound alterations to multiple objects, paths, and colors at a time. Alterations include moving multiple objects at once, shrinking, rotating, or duplicating them. It also allows you to make adjustments based on colors and blurs.
Zoom Tool 
(Z) This is self-explanatory for most of you. The Zoom Tool lets you zoom in and out (when holding the shift key) of your drawing area. You can also use the – (minus) and + (plus) keys to zoom.
The Zoom tool allows you to increase or decrease your view of the canvas. You can zoom in to see fine details, zoom out to get a more complete view of the canvas, or set the view ratio to 1:1 in order to see how the canvas looks at full size.
Measure Objects Tool 
(M) The Measure Objects Tool seems to be designed to be used in conjunction with the Geometric Construction Tool. When you click and drag it across your vectors, it’ll mark (in whatever units you choose for your document) and measures the distance of spaces between paths.

The Measurement tool allows you to assess the length, width, height, radius, or diameter of specific objects in the following units of measurement: px, mm, pc, pt, in, cm.
Rectangle Tool 
(R) The Rectangle Tool lets you create rectangles and squares. When you create your rectangle, it isn’t a path, it’s an object. When a rectangle is selected, you’ll see some handles at three of the corners. The squares let you resize your rectangle. The circle in the upper right-hand corner will split into two circles, but they will let you adjust the roundness of the rectangle’s corners until it turns into an ellipse. To convert your rectangle into an editable path, go to the Menu Bar >> Path >> Object to Path. Or use the keystroke, Control/Command-Shift-C.
The Squares and Rectangles tool is used to create 4-sided vector objects, including squares and rectangles. The tool allows you to create rectangles with either perfect right angle corners or rounded corners to varying degrees.
3D Box Tool 
(X) This tool will let you create live 3D boxes in Inkscape. When you create your first 3D box, you’ll find handles for all three vanishing points; X, Y, and Z. There are also handles on the box that allows you to adjust the width, depth, and height. The box can be directly edited as paths with the Node Tool.
The 3D Box Tool allows you to work in 1-point, 2-point, and 3-point perspectives. Within the tool settings, you can adjust the angle of the vanishing point for each axis and you can swap between making a specific vanishing point finite or infinite. This means you can either adjust your vanishing point manually or your vanishing point can be isometric (or have that flat look for a specific axis).
The 3D Boxes tool allows you to quickly create three-sided vector boxes that appear as if they’re three-dimensional. The X, Y, and Z axis can be adjusted indepently in order to determine the box’s width, height, and depth.
Ellipse/Arc Tool 
(E) The Ellipse/Arc Tool is for all of your elliptical needs. There will be two square handles to adjust the width and height. You’ll also find a circle handle on the side of your object. That handle will separate into two circle handles that can be used to partition off how much of the ellipse you’ll want to use for an arc or curve. The fill within the ellipse will remain up to the two circle handles. Dragging either of the circle handles past to center of the ellipse object will create a corner that extends to the midpoint. To convert an ellipse object into a path, go to the Menu Bar, select Path, then Object to Path. Or use the keystroke, Shift-Control/Command-C.
Inkscape - Arc/ellipse tool and a break down of an ellipse in Inkscape
The Circles, Ellipses, and Arcs tool can be used to create vector objects with curved edges, including circles and ellipses. The tool also allows you to create partial ellipses in pie chart style.
Star/Polygon Tool 
(Shift-8) The Star/Polygon Tool creates objects that can be formed into stars or polygons. You’ll find two handles on your newly created objects, one to adjust the points, and the other to adjust the inside corners. The settings, under the Menu Bar, will let you change the number of corners, the Spoke Ratio ~ a.k.a. the depth of the internal corners, the roundness of the corners, and there’s a setting that lets you turn your polygon into wacky abstractions. There’s also a reset button in case things get a little funky.

The Stars and Polygons tool allows you to create both stars and polygons. When creating stars, you’ll be able to determine the number of corners the star has, the spoke ratio between each star, and you can choose to give your star rounded corners as well. When creating polygons, you’ll be able to determine the number of sides/corners and you can choose to make them rounded if you’d like.
Spiral Tool 
(I) For all of your spiral creation needs. You’ll find two different handles on your new spiral. One handle on the inside and one on the outside.
The Spirals tool is used to create vector paths that follow a spiral trajectory. The tool allows you to adjust the number of turns the spiral has as well as its divergence from its center point.
Pencil Tool 
(P) The Freehand Tool lets you create editable paths, ideally with a graphics tablet. You can continue a path by starting at a node.
The Draw Freehand Lines tool is used to draw vector paths that follow the trajectory of your hand movement.
Pen Tool 
(B) For creating bezier curves and straight lines. You have to click and drag to pull out a node’s handles. Handles can’t be adjusted on the fly like in Adobe Illustrator. Use the Node Tool to tweak nodes and curves. To continue a path, click on top of the node you want to continue from. Then you can add more to your path. To close an open path, use the keystroke Shift-Return.
The Bezier Pen is used to create vector paths by creating a series of individual points known as nodes. The paths can have straight edges or curved edges.
Calligraphy Tool 
(C) The Calligraphy Tool lets you create lines with varying widths. The end result isn’t a skeletal stroke, but a newly created object with just a fill. The Calligraphy Tool can be used with a graphics tablet to paint, ink, and draw with. It has different presets that create various effects as you draw. I recommend clicking the Path menu >> Simplify (Ctrl-L) to reduce your nodes and smooth your strokes.
The Draw Calligraphic or Brush Strokes tool allows you to create freehand vector objects using a classic brush stroke and shape of your choosing.
Type Tool 
(T) With the text tool you can click in a spot and start typing or click and drag to create a text box reminiscent of your favorite page layout software. The Tool Settings above have all of the necessary settings to manipulate and adjust your text.
The Text Objects tool is used to create vector text and wording of your choosing. It allows you to flow your text into a bounding box, or simply generate it all on one line. You can also adjust the font, size, orientation, spacing between letters and words, as well as various other adjustments.
Spray Tool 
(A) The Spray Tool duplicates the last selected object in clusters as you drag your cursor across the canvas. The Spray Tool also has options that scatter and rotate your duplicates.
The Spray Objects tool allows you to generate vector objects by spraying them onto the canvas based on a shape of your choosing.
Eraser Tool 
(E) The Eraser Tool will create a temporary path that will delete any object beneath it. The object doesn’t need to be selected to be affected. Plus you can use a pressure-sensitive tablet with the eraser tool.
The Erase tool is used to delete segments of vector paths in a freestyle technique that is based on the trajectory of your hand movement.
Paint Bucket Tool 
(U) The Fill Tool creates new vector objects based on the area that you click in. For example, if you click within an object, you create a new vector shape based upon the bounds created by the stroke. Shapes can also be created within closed-off empty spaces.
The Fill Bounded Areas tool, commonly known as the bucket fill tool, allows you to fill empty spaces with a predetermined fill color. In order for the tool to work, the area you’re filling in must be completely surrounded by a closed path. It will not work on empty spaces that bleed out into the open canvas.
Gradient Tool 
(G) The Gradient Tool can be used to apply gradients to your type, objects, and paths. Tool Settings allow you to set the type of gradient that you’re using, pick a gradient preset, whether you want to link to a gradient preset (allowing you to change the gradation of multiple objects at once), if you wish to flip the gradient, how to repeat it, choose which stop to edit (color), the offset (location) of your stops not on the ends), and if you want to add or delete a specific stop.

I think the Gradient Tool truly shines as a tool to adjust the gradient within your object. Each gradient has a path with two main handles (for each color/stop), which can be used to position where you want each color to begin. Double-clicking with the Gradient Tool on that gradient path will allow you to add new colors to your gradient. Fill and Stroke Pallet will allow you to further manipulate your gradient, changing both the color and transparency.
The Create and Edit Gradients tool allows you to give vector objects multiple colors that fade into each other, otherwise known as gradients. The tool also allows you to edit the gradients based on colors used, number of colors, and the position of the colors relative to the object the gradient is being applied to. The gradients can follow either a linear (straight) or radial (rounded) path.
Mesh Tool 
The Mesh Tool allows users to create gradient meshes within an object’s fills or strokes. Set the number of Rows and Columns within the Tool Settings. Then double-click in the fill or stroke to create your mesh. Double-clicking on a path within the mesh will create a new path that will run horizontally or vertically. The nodes on the mesh can be assigned their own color and have handles that manipulate the color’s spread.
A breakdown of the mesh tool and its settings in Inkscape 1.2.
A breakdown of the Mesh Tool in Inkscape 1.2: 1) New standard mesh. 2) New circular mesh. 3) Create mesh in Fill. 4) Create mesh in stroke. 5) Number of Rows in the new mesh. 6) Number of Columns in the new mesh. 7) Toggle selected between Bezier and Line. 8) Make selected sides elliptical. 9) Pick a color from the object behind the mesh. 10) Scale mesh to fit inside bounding box. 11) SVG Warning. 12) Choose a method of smoothing colors. 13) Node handle to adjust color spread. 14) Mesh Node where the color emanates from.
The Meshes tool is used to give vector objects a gradient that follows a grid (mesh) or a cone shape (conical).
Dropper Tool 
(D) The Dropper works just like any other dropper tool in the sense that it can pick up colors anywhere on your canvas. If you have another object selected while using the Dropper Tool, it’ll change the fill to that color. Shift-Click will change the stroke color. Holding the Alt/Option key changes the color to the inverse of the color that you selected.
The Pick Colors From Image tool, commonly referred to as the dropper, allows you to set an object’s fill and stroke color based on another object’s color. The tool allows you to sample colors from both vector and raster images.
Connector Tool 
(O) The Connector Tool is great for people who create diagrams. Basically, the Connector Tool’s sole use is to let you create lines that link to your objects. Once those lines are created, they’ll remain attached to your objects. If you have two squares linked together, and you choose to move one of them, the line will stretch/squash, and follow the square you move.
The Diagram Connectors tool allows you to create diagrams by generating paths and boxes that link objects together.

Geometric Construction Tool: (Shift-F9) This tool is specifically designed for folks in engineering and scientific drawing. (a.k.a. ~ you use CAD software on a day-to-day basis) For the rest of us, how to use it isn’t so simple. I wrote a breakdown of how to use the Geometric Construction tool to read.
Page Tool: (*) The Page Tool in Inkscape allows you to adjust and create new pages on the fly. A Page in Inkscape is the area that will contain the actual artwork that you wish to export for print or screen.
