https://docs.katalon.com/display/KD/Object+Spy+Preferences is saying:
This ability to change hotkeys for Object Spy only affect Chrome browser. Other browsers will be considered for future releases.
On ver 5.4.1 I tried changing hotkey for Object Spy fro Alt+` to Alt+a, it successfully affects Firefox as well.
I think the documentation should be revised so that it say “this affects Chrome and Firefox”. Also the settings dialog should be changed.

This documentation error is/was significant for me because I can not use Chrome with Katalon for Recording/Replaying/Spying on my office PC (why? see http://forum.katalon.com/discussion/6150/google-chrome-crashed-on-my-pc-----2-reasons-found).
I can use Firefox on the PC. But the ability of Spy Web’s hotkey changing is documented not applicable to Firefox; therefore I have to give up Spy Web on my office PC. — This was how I thought.
Now I know the documentation is outdated, the ability of Spy Web’s hotkey changing affects Firefox as well. Now I have realized I can use Spy Web.
