Situation
I am using Brave’s vertical tabs and Vimium. The default keybindings for browsing between tabs is SHIFT + J/K for previous and next tab, but when I press J I want to navigate to the next tab instead of the previous one.
Solution
The solution is to remap the keybindings in the Vimium options.
map K previousTab
map J nextTab
