Use keyboard to move the cursor in the command field

Rhino Rhino for Windows
1

Hello.

I would like my arrow keys (or modified arrows keys like shift-left and shift-right) to control the cursor in the command field rather than nudge or rotate the view. I have searched, but not found a way to do this. I find it inconvenient to have to click for the position of the cursor when editing a command. For instance, if I am entering a coordinate point of 1,10/sin(32),20/sqrt(2) it is useful to use the arrow keys to move the cursor.

For reference, I’m on Rhino 8.

Thank you!

I have managed to get this to work with AutoHotKey v2.0. Below is the script. I currently have the functions mapped to Ctrl-Arrow. I have two sets of arrow keys in my keyboard setup, so I will map the second set to the modified Ctrl-Arrow keys.

You need to change the command window font to Lucida Console (because it is a fixed width font).
