I'm noticing errant behaviour with some standard key sequences with Vim 8.1 on wsltty. The correct behaviour is displayed when inside wsltty's standard terminal, so until proven otherwise I'm assuming it's an issue on Vim's end.
- When I'm in insert mode and go to enter any uppercase letter by holding
Shiftand the relevent key, it maps to undo, i.e. performs the deletion/insertion and updates the status bar with a message like '1 line less; before #4; 1 second ago'
- When I'm in insert mode and enter a forward slash, a new line is inserted above the current line with an 'o' at the beginning of it, e.g:
--BEFORE-- Some words are entered here█ --AFTER-- Some words o█ are entered here
.vimrc is here. I have no mappings to these key sequences. They work correctly in command-line mode, normal mode and inside gvim. I'm truly puzzled as to the cause of this odd behaviour.
