The number of lines whose Excluded state is to be toggled. If specified as 0 or omitted, 1 is assumed.
The TX command will toggle the Excluded state of the lines within the range of the command.
Lines that formerly were excluded will become unexcluded, and lines that formerly were unexcluded will become excluded.
It is possible to use the LINE primary command to apply TX to a range of lines.
It is also possible to map TX to a key to quickly toggle the Excluded status of a single line.
Here is an example mapping to do that, which will keep the cursor on the current line when finished:
