A list of Vim commands that you'll actually use.

Movement

Syntax	Description
`h j k l`	Move the cursor up, down, left, right
`e w`	Move forwards to end of word, move forwards to the start of a word
`b`	Move backwards to start of word
`i a`	Insert/append, goes to the left/right side of current character
`I A`	Insert at the beginning of the line, append at the end of the line
`o O`	Insert line below/above
`%`	Jump to matching parenthesis/quote
`f[CHAR]`	Jumps to next occurrence of [CHAR]
`[NUMBER]G`	Jumps to line [NUMBER]
`g_`	Jumps cursor to the last non-whitespace character in the line

Editing

Syntax	Description
`d`	Deletes. Can combine with movement, i.e. dw deletes the word to the right of the cursor, db deletes to the left of the cursor
`x X`	Deletes single character before/after cursor
`daw`	Deletes the entire word under the cursor
`c[i/a][DELIMITER]`	Select everything inside DELIMITER (such as `""` or `()`, and DELIMITER = `w` means current word), and replace it (enters INSERT mode). Using i means inner, i.e. the word inside the delimiter, while a will include the delimiter
`v[i/a][DELIMITER]`	Same thing as above but selects (visually) instead of changing the word
