Since console apps has no knowledge of gestures, if we can convert pageUp/Down gestures to keys or mouse wheel events, it will enable more creative usages in termux.
For example, current gesture support is non-functional when using less in neovim terminal mode.
to reproduce the bug, enter neovim terminal mode with:
$ nvim -c term
Inside the neovim terminal mode, run
$ less txtfile
Then pageUp/Down gestures trigger neovim quit terminal insert mode and thus make it nonfunctional.
Running less in neovim terminal mode in linux, pressing pageUp/Down keys or mouse wheel works perfectly.
