Log:
2008-03-28 Sven Neumann <sven gimp org>
* data/tips/gimp-tips.dtd
* data/tips/gimp-tips.xml.in
* app/dialogs/tips-parser.[ch]: reverted some of the changes
from
yesterday. The simplification went too far and we inadvertently
lost an important feature.

- You can get context-sensitive help for most of GIMP's features by
- pressing the F1 key at any time. This also works inside the menus.
- </_tip>
- <_tip level="beginner">
- 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

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

- <_tip level="beginner">
- When you save an image to work on it again later, try using XCF,
- 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, ...
- </_tip>
- <_tip level="beginner">
- Most plug-ins work on the current layer of the current image. In
- some cases, you will have to merge all layers (ImageâFlatten Image)
- if you want the plug-in to work on the whole image.
- </_tip>
- <_tip level="beginner">
- If a layer's name in the Layers dialog is displayed in <b>bold</b>,

- using LayerâTransparencyâAdd Alpha Channel.
- </_tip>
- <_tip level="beginner">
- 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 (ImageâModeâRGB), add an alpha-channel
- (LayerâTransparencyâAdd Alpha Channel) or flatten it
- (ImageâFlatten Image).
- </_tip>
- <_tip level="beginner">
- You can adjust or move a selection by using <tt>Alt</tt>-drag.
- If this makes the window move, your window manager uses the

- You can drag a layer from the Layers dialog and drop it onto the

- GIMP supports gzip compression on the fly. Just add <tt>.gz</tt>

- After you enabled "Dynamic Keyboard Shortcuts" 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

- You should probably disable "Dynamic Keyboard Shortcuts"
- afterwards, to prevent accidentally assigning/reassigning shortcuts.

- If your screen is too cluttered, you can press <tt>Tab</tt>
- in an image window to toggle the visibility of the toolbox
- and other dialogs.

- <_tip level="advanced">
- <tt>Ctrl</tt>-clicking on the layer mask's preview in the Layers dialog
- toggles the effect of the layer mask. <tt>Alt</tt>-clicking on the layer

- <_tip level="advanced">
- <tt>Ctrl</tt>-click with the Bucket Fill tool to have it use
- the background color instead of the foreground color.
- Similarly, <tt>Ctrl</tt>-clicking with the eyedropper tool
- sets the background color instead of the foreground color.
- </_tip>
- <_tip level="advanced">
- <tt>Ctrl</tt>-drag with the Rotate tool will constrain the
- rotation to 15 degree angles.

- 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.
- </_tip>
- <_tip level="advanced">
- If some of your scanned photos do not look colorful enough, you
- can easily improve their tonal range with the "Auto"
- button in the Levels tool (ColorsâLevels). If there are any
