What are uBlock Origin hotkeys?
uBlock Origin certainly has hotkeys, as I've invoked the program accidentally by pressing keys and the developer has participated in a related discussion on the Github page.
In particular a hotkey for the element picker would improve workflow as I already have thousands of cosmetic and network filters.
uBlock Origin hotkeys (shortcuts) can now be modified on the "shortcuts" tab in the extension settings (1.16.16 release, Firefox-only).
UPDATE: Use "Manage extension shortcuts" in about:addons
Note that native Firefox shortcuts can't be overridden.
For Chromium or Chrome:
Now you can add custom shortcut from extensions page.
Go to: Menu -> More Tools -> Extensions
.
Click on left menu button and Keyboard Shortcuts
.
Find uBlock
and assign your shortcut like below screenshot:
