Use I to insert at the first non-blank on the line. gi returns to the last insertion point and re-enters Insert mode.
Commands you practise
I
Press I to start inserting at the first non-blank character. It instantly bypasses leading indentation, no matter where your cursor is.
gi
Jump straight back to your last edit and resume Insert mode. Perfect for when you wander off to inspect code and need to quickly get back to typing.
Levels
Silence Three Steps (easy): Comment out the three setup steps that should not run.
Return to the Handler (medium): Drop the stray letter, finish the half-typed handler name, and return the registration.
Where You Left Off (hard): Drop the stray letter, finish the half-typed row limit, then await both client calls.
Each level opens a real Neovim session in your browser with a start file and a target file. Edit one into the other in as few keystrokes as you can, then race the vimbot's solution.
