"Change Set: MorphPosSizeUsingKeyboard-dgd Date: 28 August 2004 Author: Diego Gomez Deck
Keyboard based fine positioning and sizing of morphs.
When a morph is sorrounded by its halo, you can position and size it using the arrow keys at your keyboard.
How to: cursor-arrow: move in 1 pixel increments. cursor-arrow + CTRL: move in 10 pixels increments. cursor-arrow + SHIFT: resize in 1 pixel increments. cursor-arrow + CTRL + SHIFT: resize in 10 pixels increments.
For morphs that handles keyboard events (like TextMorph) just point the mouse to any place but morph's bound.
