It would be really nice if the escape key (esc) closed the browser extension window. I often login to Bitwarden chrome extension using keyboard shortcuts, but don’t immediately need to do anything with it but the extension window remains open.
I not only press Ctrl + Shift + Y to open the Bitwarden extension window. I also use this hotkey to close it again. Not exactly what you requested, but perhaps this is good enough.
Definitely good enough, thank you.
Good enough to be called “solved” ?
Also, I think this recent PR would probably solve the issue too whenever the next release is released.
In the meantime, ⌘ + Shift + Y seems to also toggle the window on macOS.
Feel free to ping if you want this feature request reopened.
