Even if I remove default Geany shortcut `cmd+space` (complete word), still MacOS system shortcut does not work. I use it for language switch (since MacOS Lion).

There is also second, may be connected problem — sometimes other shortcuts do not work completely, as if Geany thinks it is in wrong locale, although typing text shows it is in EN locale. Switching to another app (`cmd+tab`), pressing TWICE `cmd+space` to switch locale and returning to Geany fixes this issue. Also none of shortcuts work on non latin locale.
