## Wand (W)

Selects a contiguous area with similarly colored pixels. With the controls below the toolbar, you can configure tolerance and whether the tool should select unconnected but similarly colored areas as well.

By pressing Ctrl, Shift or Shift+Ctrl when using the tool, you can subtract from the selected area, add to it, or intersect it with the newly selected region, respectively.

## Select with pencil (I)

Selects with a 1-pixel-wide (non-antialiased) brush.

## Transform (F)

The selection can be resized with the blue handles, rotated with the red handle, or moved around. By pressing Shift you can transform the selection in perspective mode, which means you can rotate the selection in 3D, skew it or move the individual corners freely.

## Crop (X)

After using the crop tool, there is no need to double-click or press Enter to apply the cropping: it is already applied but can be adjusted with the handles displayed at the corners of the cropped image. The areas removed from the original image are still visible with less alpha to aid with adjustment. Switching to another tool hides these adjustment guides.

## Set cursor hot spot (H)

Sets cursor hot spot, i.e. the point where clicking occurs. This is typically the tip of an arrow or the center of a cross. Clicking outside the image removes the hot spot. The tool sets the same hot spot for all frames of the current page. Ctrl-click to set the hot spot for the current frame only.

## Eyedropper (Y)

Picks foreground (left mouse button) or background color (right mouse button) from the image.

## Retouch (U)

Applies a filter with a brush. Available filters: Blur, Sharpen, Dodge, Burn, Hue, Sponge. Can be configured with the controls below the toolbar.

## Rectangle (R)

Draws a rectangle with outline only, fill only, or outline and fill. Right mouse button swaps foreground and background colors. Behaves as eraser if the transparent color is selected.

## Ellipse (J)

## Text (T)

Inserts text. The text can be edited after insertion by clicking on it again with the Text tool. Note that the text cannot be edited any more if the file is saved and reloaded, or if the Transform tool is used on the inserted text.

## Pencil (P)

Draws a 1-pixel-wide line that can be antialiased or not. Can be configured with the controls below the toolbar. Left mouse button draws with foreground color, right button with background color. Behaves as eraser if the transparent color is selected.

## Brush (B)

Left mouse button draws with foreground color, right button with background color. Works as an eraser if the transparent color is selected. If parts of the image are selected (e.g. with the "Select rectangle" tool), the brush will only draw in the selected area. Shape, size and other options can be configured with the controls below the toolbar.

## Eraser (E)

Behaves like the brush tool but replaces the area with transparency, or reduces alpha if the eraser strength is set to a smaller value in the tool settings panel below the toolbar.

## Recolor (Q)

Replaces the background color with the foreground color on the image. Tolerance and other options can be configured with the controls below the toolbar. Right mouse button swaps foreground and background colors.

## Bucket fill (K)

Fills contiguous, similarly colored areas with the foreground color. Right mouse button fills with background color. With the controls below the toolbar, you can configure tolerance and whether the tool should fill unconnected but similarly colored areas as well.

## Gradient fill (G)
