vscode vim

gd - jump to definition. gq - on a visual selection reflow and wordwrap blocks of text, preserving commenting style. Great for formatting documentation comments. gb - adds another cursor on the next word it finds which is the same as the word under the cursor. af - visual mode command which selects increasingly large blocks of text. For example, if you had "blah (foo [bar 'ba|z'])" then it would select 'baz' first. If you pressed af again, it'd then select [bar 'baz'], and if you did it a third time it would select "(foo [bar 'baz'])". gh - equivalent to hovering your mouse over wherever the cursor is. Handy for seeing types and error messages without reaching for the mouse!
