Shortcut conflict on Gnome

[ml thlf me]

Hi easytag user's

I'm having a keyboard shortcut problem when easytag is installed (on 
Gnome). My shortcut <Alt + e> allows me to open "Files", and as soon as 
easytag is installed this same shortcut open easytag. The custom setting 
in the Gnome settings does not change anything.

After some similar research I have not found answers.

If you have some solutions, i take it !

System informations :
4.16.4-1-MANJARO
Gnome Shell v3.28.1
Easytag 2.4.3
Files 3.28.1-784b3eaab

Thank.
