@bobiq you can’t change shortcuts yet. That said, it is currently a capability in Brave Nightly and will be making its way to Release (which is current normal version) in a while. I’m not sure off the top of my head which version will appear, but will arrive by 1.54.65 which is current Nightly version.
@bobiq just FYI, the latest Brave update to Release gives you the option to change shortcuts. So if you update to 1.56.9 you’ll be able to see that at
Shortcuts or can just put
brave://settings/system/shortcuts to get to it.
