I have ( i don't remember if this is default) Change octave keys on F11 (octave down) and F12 (octave up)

During file selection inside the browser this keys stop working and do not change the octave, so when testing instruments and needing to change the octave up or down I have to close the browser, change the octave and come back to the browser again.

(This bug is for furnace internal browser, not windows system browser)

I was told that the numpad keys + and - do this but I have a tenkeyless keyboard, so I do not have such keys.

Expected result: Keys should work inside the file selector browser.
