<big>Welcome to the GIMP!</big>

<tt>Alt</tt>-click on the layer mask's preview in the Layers dialog toggles viewing the mask directly.

<tt>Ctrl</tt>-click on the layer mask's preview in the Layers dialog toggles the effect of the layer mask.

<tt>Ctrl</tt>-click with the Bucket Fill tool to have it use the background color instead of the foreground color.

<tt>Ctrl</tt>-drag with the Rotate tool will constrain the rotation to 15 degree angles.

<tt>Shift</tt>-click on the eye icon in the Layers dialog to hide all layers but that one. <tt>Shift</tt>-click again to show all layers.

A floating selection must be anchored to a new layer or to the last active layer before doing other operations on the image. Click on the &quot;New Layer&quot; or the &quot;Anchor Layer&quot; button in the Layers dialog, or use the menus to do the same.

After you enabled &quot;Dynamic Keyboard Shortcuts&quot; in the Preferences dialog, you can reassign shortcut keys. Do so by bringing up the menu, selecting a menu item, and pressing the desired key combination. If &quot;Save Keyboard Shortcuts&quot; is enabled, the key bindings are saved when you exit GIMP.

Click and drag on a ruler to place a guide on an image. All dragged selections will snap to the guides. You can remove guides by dragging them off the image with the Move tool.

If some of your scanned photos do not look colorful enough, you can easily improve their tonal range with the &quot;Auto&quot; button in the Levels tool (Layer-&gt;Colors-&gt;Levels). If there are any color casts, you can correct them with the Curves tool (Layer-&gt;Colors-&gt;Curves).

If you stroke a path (Edit-&gt;Stroke Path), the paint tools can be used with their current settings. You can use the Paintbrush in gradient mode or even the Eraser or the Smudge tool.

If your screen is too cluttered, you can press <tt>Tab</tt> multiple times in an image window to hide or show the toolbox and other dialogs.

Most plug-ins work on the current layer of the current image. In some cases, you will have to merge all layers (Image-&gt;Flatten Image) if you want the plug-in to work on the whole image.

Not all effects can be applied to all kinds of images. This is indicated by a grayed-out menu-entry. You may need to change the image mode to RGB (Image-&gt;Mode-&gt;RGB), add an alpha-channel (Layer-&gt;Transparency-&gt;Add Alpha Channel) or flatten it (Image-&gt;Flatten Image).

Pressing and holding the <tt>Shift</tt> key before making a selection allows you to add to the current selection instead of replacing it. Using <tt>Ctrl</tt> before making a selection subtracts from the current one.

The GIMP can undo most changes to the image, so feel free to experiment.

The GIMP supports gzip compression on the fly. Just add <tt>.gz</tt> (or <tt>.bz2</tt>, if you have bzip2 installed) to the filename and your image will be saved compressed. Of course loading compressed images works too.

The GIMP uses layers to let you organize your image. Think of them as a stack of slides or filters, such that looking through them you see a composite of their contents.

The layer named &quot;Background&quot; is special because it lacks transparency. This prevents you from moving the layer up in the stack. You may add transparency to it by right-clicking in the Layers dialog and selecting &quot;Add Alpha Channel&quot;.

To create a circle-shaped selection, hold <tt>Shift</tt> while doing an ellipse select. To place a circle precisely, drag horizontal and vertical guides tangent to the circle you want to select, place your cursor at the intersection of the guides, and the resulting selection will just touch the guides.

When using a drawing tool (Paintbrush, Airbrush, or Pencil), <tt>Shift</tt>-click will draw a straight line from your last drawing point to your current cursor position. If you also press <tt>Ctrl</tt>, the line will be constrained to 15 degree angles.

When you save an image to work on it again later, try using XCF, the GIMP's native file format (use the file extension <tt>.xcf</tt>). This preserves the layers and every aspect of your work-in-progress. Once a project is completed, you can save it as JPEG, PNG, GIF, ...

You can adjust or move a selection by using <tt>Alt</tt>-drag. If this makes the window move, your window manager uses the <tt>Alt</tt> key already. Try pressing <tt>Shift</tt> at the same time.

You can adjust the selection range for fuzzy select by clicking and dragging left and right.

You can create and edit complex selections using the Path tool. The Paths dialog allows you to work on multiple paths and to convert them to selections.

You can drag a layer from the Layers dialog and drop it onto the toolbox. This will create a new image containing only that layer.

You can drag and drop many things in the GIMP. For example, dragging a color from the toolbox or from a color palette and dropping it into an image will fill the current image or selection with that color.

You can draw simple squares or circles using Edit-&gt;Stroke Selection. It strokes the edge of your current selection. More complex shapes can be drawn using the Path tool or with Filters-&gt;Render-&gt;Gfig.

You can get context-sensitive help for most of the GIMP's features by pressing the F1 key at any time. This also works inside the menus.

You can perform many layer operations by right-clicking on the text label of a layer in the Layers dialog.

You can press or release the <tt>Shift</tt> and <tt>Ctrl</tt> keys while you are making a selection in order to constrain it to a square or a circle, or to have it centered on its starting point.

You can save a selection to a channel (Select-&gt;Save to Channel) and then modify this channel with any paint tools. Using the buttons in the Channels dialog, you can toggle the visibility of this new channel or convert it to a selection.

You can use <tt>Alt</tt>-<tt>Tab</tt> to cycle through all layers in an image (if your window manager doesn't trap those keys...).

You can use the middle mouse button to pan around the image, if it's larger than its display window.

You can use the paint tools to change the selection. Click on the &quot;Quick Mask&quot; button at the bottom left of an image window. Change your selection by painting in the image and click on the button again to convert it back to a normal selection.
