Various window shortcut keys
- Settings window: "r" for Reload, "a" for Auto-Save, "s" for Save.
- Screen size: "h" to set height
- Spray menu: "s" for Size, "d" for Delay, "m" for Mono-Flow, "i" for Init
- Text Menu: "t" to enter text, "s" to enter size, show underscore for AA, Bold, Italic
- Palette window: "w" for Swap, "t" for Histo, fix "i" for Flip, show underscore for Merge, Used
- Transform menu: replace X and Y labels with W and H, and make them also shortcuts. I have renamed these labels so that it does not conflict with the existing Mirror "X" and "Y" buttons.
