user: How do I use Toolbar in Blender? Include parameters, examples, warnings and best practices.

assistant: # Toolbar

Selection tools
:   [Tweak](../../../interface/selecting.html#tool-select-tweak)
    :   Select or move.

    [Select Box](../../../interface/selecting.html#tool-select-box)
    :   Select images by dragging a box.
        All images that intersect the box will be selected.

    [Select Circle](../../../interface/selecting.html#tool-select-circle)
    :   Select images by dragging a circle. All images that intersect the path of
        the circle will be selected.

    [Select Lasso](../../../interface/selecting.html#tool-select-lasso)
    :   Select images by drawing a lasso.

Cursor
:   Lets you move the [2D Cursor](sidebar.html#editors-sequencer-preview-2d-cursor) by clicking or dragging with `LMB`.

    While dragging, you can press `X` or `Y` to constrain movement to an axis.

    If you need extra precision, you can hold `Shift` to move the cursor more
    slowly than the mouse, or type a number to move it by an exact amount.

    The header shows how far the cursor has traveled, including the distance along each axis.

    Instead of this tool, you can also drag the mouse while holding `Shift`-`RMB`
    (works with all tools) or adjust the 2D Cursor Location in Sidebar ‣ View.

Move `G`
:   Lets you move the selected images by dragging with `LMB`.
    Alternatively, you can press `G`, move the mouse, and finally click `LMB` to confirm
    (or `RMB` to cancel).

    If the [Active Tools](display/gizmos.html#bpy-types-spacesequenceeditor-show-gizmo-tool)
    gizmo is enabled, you can drag one of the colored arrows to only move along that one axis.
    You can also press `X` or `Y` while moving: press once to constrain to the
    corresponding global axis, a second time to constrain to the local axis,
    and a third time to remove the constraint again. Yet another way is to hold
    `MMB` and move the mouse horizontally or vertically.

    If you need more precision, you can do one of the following while moving:

    - Hold `Shift` to move more slowly.
    - Type a number to move by an exact amount.
    - Use the arrow keys.

    The header shows how far the image has moved, including the offset along each axis.

    Instead of using this tool, you can also adjust the [Position](../sequencer/sidebar/strip.html#bpy-types-striptransform-offset)
    in the Sidebar’s *Strip* tab (only available in the *Sequencer* and *Sequencer & Preview* modes).

Rotate `R`
:   Lets you rotate the selected images by holding `LMB` and moving the mouse in a circle.
    Alternatively, you can press `R`, move the mouse, and finally click `LMB` to confirm
    (or `RMB` to cancel).

    Images are rotated around the [Pivot Point](controls/pivot_point.html#bpy-types-sequencertoolsettings-pivot-point),
    so if it’s off-center, the images will not just rotate but also move around it.

    If you need more precision, you can do one of the following while rotating:

    - Hold `Shift` to rotate more slowly.
    - Hold `Ctrl` to rotate in increments of 5 degrees.
    - Type a number to rotate by an exact amount.
    - Use the arrow keys.

    The header shows how much the image has rotated.

    Instead of using this tool, you can also adjust the [Rotation](../sequencer/sidebar/strip.html#bpy-types-striptransform-rotation)
    in the Sidebar’s *Strip* tab (only available in the *Sequencer* and *Sequencer & Preview* modes).

Scale `S`
:   Lets you resize the selected images by dragging with `LMB`.
    Alternatively, you can press `S`, move the mouse, and finally click `LMB` to confirm
    (or `RMB` to cancel).

    If the [Active Tools](display/gizmos.html#bpy-types-spacesequenceeditor-show-gizmo-tool)
    gizmo is enabled, you can drag one of the colored lines to only scale along that one axis.
    You can also press `X` or `Y` while scaling: press once to constrain to the
    corresponding global axis, a second time to constrain to the local axis,
    and a third time to remove the constraint again. Yet another way is to hold
    `MMB` and move the mouse horizontally or vertically.

    Images are scaled around the [Pivot Point](controls/pivot_point.html#bpy-types-sequencertoolsettings-pivot-point),
    so if it’s off-center and you scale down, the images will not just become smaller
    but also move towards it.

    If you need more precision, you can do one of the following while scaling:

    - Hold `Shift` to scale more slowly.
    - Hold `Ctrl` to scale in increments of 10%.
    - Type a number to scale by an exact factor (e.g. `.5` to make it half the size).
    - Use the arrow keys.

    The header shows the current scale factor.

    Instead of using this tool, you can also adjust the [Scale](../sequencer/sidebar/strip.html#bpy-types-striptransform-scale)
    in the Sidebar’s *Strip* tab (only available in the *Sequencer* and *Sequencer & Preview* modes).

Transform
:   Lets you move, rotate, and scale images all using one tool.

    [image reference removed]

    The Transform tool

    It works as follows:

    - Drag the cross in the center to move the image.
    - Drag the dot on the protruding line to rotate.
    - Drag one of the corners to scale equally along both axes.
    - Drag one of the sides to scale along just one axis.

Sample
:   Lets you sample a pixel’s color by holding `LMB`. The editor will show the following information
    about it on the bottom:

    - The X and Y coordinates, in pixels relative to the top left corner.
    - The red, green, blue, and alpha components of the pixel, as decimal values between 0 and 1.
    - The red, green, and blue components of the pixel with [Color Management](../../../render/color_management/index.html) applied.
    - The hue, saturation, value, and luminance components of the pixel with Color Management applied.

    Sample tool example.

[Annotate](../../../interface/annotate_tool.html#tool-annotate-freehand)
:   Draw free-hand annotations.

    [Annotate Line](../../../interface/annotate_tool.html#tool-annotate-line)
    :   Draw a straight line annotation.

    [Annotate Polygon](../../../interface/annotate_tool.html#tool-annotate-polygon)
    :   Draw a polygon annotation.

    [Annotate Eraser](../../../interface/annotate_tool.html#tool-annotate-eraser)
    :   Erase previously drawn annotations.
