Ctrl + / or Comment / uncomment selected text in the context menu of the editor comments or uncomments the current line or all lines of the selection.

• All selected lines get the same state: if at least one line is not commented, all lines are commented; if all lines are commented, they are uncommented. Lines which are already commented are not commented twice. Empty lines are skipped.
• A selection which ends at the beginning of a line does not include this line.
• The comment character is put after the indentation of the line.
• The selection stays, so the same lines can be uncommented with the next Ctrl + /. Edit » Undo reverts the whole change in one step.

▲ ABB (RAPID)

• Lines are commented with !.
• A collapsed routine is expanded when its lines are changed.
• When the selection contains the first or the last line of a MODULE / PROC / FUNC / RECORD without its pair, the status bar shows a warning - check the structure of the module.

▲ Yaskawa (JBI)

• Lines are commented with ' (comment instruction).
• Only the program lines between NOP and END are changed; the job header, NOP and END are skipped.
• A commented motion instruction ('MOVJ ...) is not a point - it is not in the point table.
• The comment instruction accepts max. 32 characters on the controller. Longer comments are shown as a warning in the status bar with the line numbers.
