How do I append the same suffix to every selected line in Visual mode?

Explanation

Visual selections are not just for direct operators; they also define an Ex range. A powerful pattern is applying :normal over '<,'> so the same normal-mode edit runs on each selected line. This lets you perform repeatable, cursor-aware edits without recording a macro or entering block mode.

How it works

• :'<,'> is the line range defined by the current Visual selection
• normal! executes raw normal-mode keys (ignores mappings)
• A; moves to end of each line and appends ;

Because this runs line-by-line through the selected range, you get deterministic edits even when line lengths differ.

Example

Select these lines in Visual line mode:

let x = 1
let y = 2
let z = x + y

Run:

:'<,'>normal! A;

Result:

let x = 1;
let y = 2;
let z = x + y;

Tips

• Swap A; for any normal edit, for example I// to prepend comments
• Use normal! (not normal) when you need predictable behavior regardless of mappings
• This approach composes well with prior narrowing via Visual selection
