Keyboard sticker manipulate

[Allerek]

Possibility for both mouse and keyboard would be better since i prefer using mouse. Arrow buttons should remain as it currently is to navigate menus since Body shop and Performance shop have it that way. Also i would suggest another method without modes swithcing like 1,2,3,4 you mentioned above, A bit more complicated but less button to press to do an action.

Position - WASD, W&S for Vertical value and A&D for Horizontal value
Rotate - Q/E for CW/CCW
Scale - [-] [+] , R F or anything possible
Slow/Fast - Hold Alt/Shift while pressing action button like Positioning or Scaling
Freelook - F1 to hide UI, just like on races. and WASD or numpad 2 4 6 8 to pan and pitch.

More:
Arrange Layer - Q to top [<] and E to bottom [>], same key with Rotate but won't complicate since it's on layers menu, not layer edit menu.
Clone - C
Delete - X
Layer edit menu - Z.

i dont think your version will be easier to write.
When bartek will include 'modes' he can check mode with

Code:

local x=mode1
local y=mode2
local z=mode3
if x then
elseif y then
elseif z then

etc 
That what you made is not intuitive at all(actual one system is better).
