This bug has not been fixed since july 2017: https://lexaloffle.com/bbs/?tid=29699

Maybe it's on AZERTY keyboards only, but it makes the SFX editor painful. Here's what this layout looks like: https://fr.wikipedia.org/wiki/AZERTY#/media/Fichier:KB_France.svg
The keyboard we frenchies use. Sorry. We love our diacritics.

• the "6" key used for upper G# also decreases current pattern.
• the "," key (right to "N") used for lower B also decreases tempo.
  Those are really annoying. There's also this which are a bit annoying but I can do with:
• numpad "+" moves to 4 patterns forward while the "-" above moves only 1 backward.
• "=" (left to Backspace) moves 1 pattern forward while underscore ("8" main key) moves 4 backward.

Hi @ElGregos -- I've fixed this for 0.2.4d (sorry it took so long!). Eventually I plan to add custom editor key bindings which may help other similar issues.
