Ability to add arrow keys to keymaps

[JitQL]

Hi,

I'm trying to start using Blender for modeling, coming from Sketchup. I'm used to constrain axis using the arrow keys instead of letters: X Axis is Right-Arrow Y Axis is Left-Arrow Z Axis is Up-Arrow Custom Axis (defined by edge under pointer) is Down-Arrow

I was able to use x, y and z keymaps in Blender but I can't use them in CAD transforms as they are not available from the list of keys to map to.

I've also adapted Shift+Arrows to constrain to planes.

Would it be possible to have Arrow keys as keymaps in CAD transforms?

At the same time, would it be conceivable to use Down-Arrow to constrain to an edge which would be hovered and Shift+Down Arrow (or other keymap) to constrain to a face?

Thanks in advance,

João
