If we could have scroll-lock or something to turn on/off the commandline, we could finally have quick shortcuts to most commands.
m - move
c - copy
r - rotate
d or del - delete
etc...
Right now shortcuts can only be by F-buttons and it's really hard to remember which does what. Especially since you can assign em yourself and there simply isn't enough to go around.
Having em defineable, but on a single-letter shortcut would speed up editing and allow 2-handed work. No more moving mouse back and forth between board/schematic and button-menu for different operations.
