Updates to about:settings prevents users from having easy access to Extension Shortcuts. Users can still manually navigate there by visiting brave://extensions/shortcuts.
Reported by _Agent of User_ on Twitter:

No link exists.
Link should exist.

No. Reproducible on current Beta, Developer, and Nightly.


I came to create an issue about this. Not sure why this was removed. I'm very dependent on it, e.g. for invoking my global password manager. Do please bring it back :)
Is there a way at all to set shortcuts for extensions currently, even if hacky? Where are they stored?
@qnxor yeah I miss it too. For now you can navigate directly to it by entering brave://extensions/shortcuts in the address bar.
I wanted to chip in myself so +1
Thanks for pointing to brave://extensions/shortcuts - I wasn't aware.
However, there is at least one bug (i should report it separately I guess). I can't set Ctrl+/ as a shortcut, whereas on Chrome I can.
EDIT: Strike that last part, I can't set Ctrl+/ on Chrome either
Interesting- we may be unintentionally hiding this. Thanks for the heads up 馃槃
Glad someone else reported this. Was bugging the heck outta me! 馃槅
@bsclifton did you discover if you were intentionally hiding this or not?
@jaminroe Unintentional.
Can still manually get to it via: brave://extensions/shortcuts
In interim we can probably get that link in there without having to do a full sidebar implementation. Possibly a link to Keyboard Shortcuts just under the "Find extensions and themes in the Web store" link.

I thought I was going insane, can't even find it by searching Brave settings, eventually discovered the "power user" link on the QuickTabs settings page, but shouldn't have to find it that way.
