The Remove Indents menu item presents a dialog that allows the user to specify the number of spaces or tabs to remove from the beginning of each of the selected (highlighted) lines. If the checkbox specifying removal of all indents is checked, UltraEdit will remove ALL indentation at the beginning of the selected lines. UltraEdit starts removing the indents beginning with the first highlighted line and ending with the last line that has at least one character selected (highlighted).
If no indentation is found at the beginning of a selected line, no changes are made to that line.
To add indentations, use the Add Indents command on the Format Menu.
