the hotkey handler has a critical section while it's handling the hotkeys. (it runs in a separate thread but sends of the hotkey functions to the main thread and wait for them to return)
createHotkey will acquire that critical section, when it adds a new entry to that list.

Therefore, calling createHotkey will wait till the hotkeyhandler has finished an interation, and the hotkley handler is waiting for the current hotkey to finish, so, deadlock

What you can do instead is spawn a timer which you disable as soon as it runs (or spawn a thread that does this)

Interesting. Are there more things like createHotkey and OnHotkey?

Not sure what you mean with this. Issues with critical sections ?

As for this case, I think it's easier to just create the hotkeys beforehand, and in the hotkey handler check if it should act or not

Yes, issues with critical sections.
