For example, make a new multi key combination using Alt-L-A, which could be some simple go command like "Go L:\path01". If you want to make a command for another path,
using "Alt-L-B", the error message would show, even if there is no combination using exactly the same sequence. The error message is thrown after the whole sequence has been
defined & is confirmed.
I used the filter for that, of course, & i saw it happening at least a dozen times. Isn't it supposed to show the double entries in a red font? I've just finishes a whole series
of commands based on AltGr-L, plus a second key, like AltGr-L-M, AltGr-L-N, AltGr-L-P, but i also saw it with the normal Alt key. The AltGr key is quite the same as pushing
Right-Alt-Control, by the way.
Here is an image, showing my current AltGr/Strg-Alt multi keys. When i made them, each one was claimed to be already present.
Hmm, i think i have a hint, what caused it. There was a plain AltGr-L hotkey, something like what you have suggested. I have deleted it, & the error message
isn't showing anymore. I was assumig, that it woul not interfere with my other hotkeys, since it was deactivated (not checked). So, it looks like also deactivated
keys are checked for double entries, also they don't generate the ususal red font duplicates. Thanks Leo.
