Delete from the SECOND comma to the end of the line. Find the first comma with f,, repeat the jump to the second with ; (semicolon), then delete to end of line with D.
keep alpha, keep beta, cut gamma, cut delta
Canonical solution: f, ; D · par: 4 keystrokes (vimgolf rules — every keypress counts).
After an f or t jump, ; repeats it forward and , repeats it backward — so f, ; ; walks comma to comma without retyping. Pair with an operator or D for precise line surgery.
Reading about keystrokes doesn't build keystrokes. Try this in a real vim buffer right now — the “Second comma's the charm” mission takes about a minute.
