Copy source string hotkey doesn't work on Microsoft Edge

By using different browsers I noticed that Alt+C hotkey doesn’t work on Microsoft Edge.
I use it very often to copy source strings and didn’t find any info on how to make it work.
Did anybody else face the same behaviour? I’m curious, which side caused the problem?

Probably Alt+shift+c would work, it’s Crowdin’s default hotkey. Can be obtained in the Editor, with hotkeys “keyboard” button (near the settings wheel). Or maybe Edge has this combination hardcoded for some other purposes. At least in Chrome and Opera cntrl + shift + c works fine for coppiung the source.
