vi has H, M, and L keybindings that move the cursor based what lines are currently on screen. It's not possible for a Vim-like extension to implement these right now, because the the vscode extension APIs don't expose this information.

Yeah. We need this for zt and zb as well. As far as I can tell there is not even a way to hack it.

#9143 - will provides a command to move the cursor. We will see if that command is suffice the needs of this issue and take the next step

@johnfn FYI Listed the cursor move commands in description which are supported now.

@sandy081 This is step in the right direction, thank you!

Unfortunately, though, we can't do everything just by moving the cursor - we need to know the position where e.g. the middle of the screen is to have full support of the Vim commands. (We could hack it by moving the cursor, recording location, then moving back, but that seems like quite the hack.)

@johnfn Can you please point me to the use cases or Vim commands where you need the middle of the screen positions.
