Begline

Key

HOME

Begline

Places the cursor on the first nonblank character in the line.

Meta Begline (F9 HOME)

Places the cursor in the first character position of the line (column one).

Returns

TrueCursor moved.

FalseCursor not moved; the cursor is already at the destination.

Example

The following macro moves the cursor to column one, then toggles between column one and the first nonblank character of the line.

toggle_begline := Left ->x Meta :>x Begline

The result of the Left function is tested to determine if the cursor is already in column one. If the cursor is in column one, PWB skips the Meta and executes Begline to move to the first nonblank character. If the cursor is not in column one, PWB executes Meta Begline to move there.

Example

This macro mimics the behavior of the BRIEF HOME key:

bhome:= Meta Begline +> Home +> Begfile

The result of Meta Begline (go to column 1 on the line) is tested to determine if the cursor moved. If the cursor moved, the test (+>) succeeds and the macro exits. If the cursor did not move, the cursor is already in column 1, so the macro advances to the home position with Home. If the cursor did not move going to the home position, the macro advances to the beginning of the file with Begfile.
