StickyKeys -esque functionality in CLI?

[tehsean]

In X, there's xkbset, which you can use to turn on StickyKeys. StickyKeys, for those unfamiliar, allows the modifier keys (Shift and Ctrl) to 'stick' until the next key press. It's handy for those with accessibility issues, and in my case, for a PC that has a thumb-board as the default text input.

Is there any way to have this same StickyKeys behavior in the terminal?

From what I've read, you can change the keymaps with wsconsctl, but it looks like /usr/include/dev/wscons/wsksymdef.h doesn't have a keycode for sticky modifiers, so even if I change the keymap, it may not help.

Also, is there a way to see the key event codes as keys are pressed?
I would like to make a shortcut key for terminal switching, as the current stroke is a 4 key monstrosity (FN+CTRL+ALT+[1-5].

Thanks in advance~
