Whitespace Trim
The 'Whitespace Trim' tool lets you select one of three modes to remove space characters from the tab-indented list in the current page of the Workspace:
Trims leading spaces from text lines, whilst ignoring any tab-indents.
Trims trailing spaces from text lines, whilst ignoring any tab-indents.
Finds double spaces in text lines, and reduces them to single ones.
The Whitespace Trim tool does not touch any tab characters. It reports on how many of each type of spaces were dealt with, and of the number of lines affected.
