Xournalpp: Ctrl+shift+(Left/right arrow) does not select text, it changes layers

[siliconninja]

I need to select a word of text (for example pressing Ctrl+shift+right arrow with the cursor at word1 selects "word1"), so I press Ctrl+Shift+left arrow or Ctrl+Shift+right arrow and that sometimes changes the layer instead. Is there a way to possibly change this default shortcut or possibly include it in the scripting feature (#919)?
I get this issue when I draw or click on the bottom > "New Layer". If I just use the background layer, this works perfectly.
I don't have much time to fully focus on contributing code because I'm in school, but I'll see what I can do if I get some free time. There is no error because the switching layers is probably configured with these keyboard shortcuts by default.

It might have something to do with ACTION_GOTO_PREVIOUS_LAYER and ACTION_GOTO_NEXT_LAYER:

We can do this when we work on #841

It's much more common to edit text than to switch layers, so I think it would be better to have CtrlShift← and CtrlShift→ select text when editing a text object The current behavior can remain for everything else.

This can be handled with #919

This is actually a bit tricky, since the layer menu item is receiving (and handling) the CtrlShift← and CtrlShift→ keypresses (in the activate callback) before the event can be handled by the TextEditor.

I encountered a comparable issue while experimenting with plugins.
A plugin that registers a plain key (let's say "e") captures this key even if the user is editing text, which technically makes it impossible to type the letter "e".

I found a workaround on https://stackoverflow.com/a/61584287/2297277 which I tested (I'm not sure where the best place would be for this code so I did not create a pull request):

g_signal_connect(window,"key-press-event",G_CALLBACK(gtk_window_propagate_key_event),NULL);
g_signal_connect(window,"key-release-event",G_CALLBACK(gtk_window_propagate_key_event),NULL);

With this, both the "e" and the Ctrl+Shift+arrows are working.
