Dynalist overwrites default Mac behavior for alt+→ and alt+←

Steps to reproduce

When the cursor is anywhere in the text I click on alt + arrow left or alt + arrow right

Expected result

I expect the default Mac behavior of moving the cursor one word to the left or right (similar as cmd+arrow keys moves the cursor from pos 1 to end).

Actual result

Dynalist navigates one level in or out of the document

Environment

macOS Mojave with Chrome 72


Additional information

It would be nice if I could at least overwrite the behavior in the keymap, but I didn’t find entries for these actions.
