Using a vanilla v2.6.0 installation I am not able to display the keyboard shortcut list using `?´.
On my Danish keyboard it’s SHIFT++.
If I press SHIFT+- (`_´) THEN I am able to get it displayed.
I found this article that describes what is going on (I am still reading it 
)
Also the handling of Danish special characters (æøåÆØÅ) need some TLC (might need a separate post, sorry…)
I have a category KK - Kælder Køleskab (= basement fridge) and a task Øl (beer).
I also have the category KF - Kælder Fryser (= basement freezer)
Using CTRL+K and searching for ø only reveals the project with that letter, not the tasks (no beer !!!),
I think I saw a note stating that changing the DB and thus change the way full text search is handled, but I’m not sure. I would like to be able to find my beer though, so what to do???
