How about it?
From what I've gathered, this shouldn't be a difficult thing to implement. This thread could be used to design and vote upon what kind of images we'd use for the key presses before it's implemented, and maybe even have someone do the code too so that jitspoe can put his time into other more important things.
Keyboard keys, triangles, arcs or arrows? What kind of coloring? Will the keys appear whenever pressed, or should they be always visible and then just add a color or something to them when they're pressed?
What should the command be?
cl_drawkeys
cl_drawpressedkeys
cl_showkeys
cl_showpressedkeys
