The BlackBerry OS 10 build-in browser had this feature.
No current browser supports this, but as a BB KeyOne user I would really appreciate that.
These were the shortcuts:
- N : Go foward one page
- P : Go back one page
- S : Find text on a page
- U : Open address bar
- K : Open bookmarks
- H : Open history
- W : Open new tab
- Q : Show all tabs
- Backspace : Close current tab (only in tab view)
- R : Open reader view
- L : Refresh page
- I : Zoom in
- O : Zoom out
- T : Go to top of a webpage
- B : Go to bottom of a webpage
- Space : Move down screen (this works already)
- Shift + Space : Move up screen (this works already)
