Keymap

• Mappings marked (LSP) require an active language server for the file.
• Mappings marked (TS) require a tree-sitter grammar for the filetype.

Normal mode

Minor modes

These sub-modes are accessible from normal mode and typically switch back to normal mode after a command.

View mode

View mode is intended for scrolling and manipulating the view without changing the selection. The "sticky" variant of this mode is persistent; use the Escape key to return to normal mode after usage (useful when you're simply looking over text and not actively editing it).

Match mode

Enter this mode using m from normal mode. See the relavant section in Usage for an explanation about surround and textobject usage.

Select / extend mode

I'm still pondering whether to keep this mode or not. It changes movement commands (including goto) to extend the existing selection instead of replacing it.

NOTE: It's a bit confusing at the moment because extend hasn't been implemented for all movement commands yet.
