Hi Damon,
Look at
Under Select tiddlers, you see two buttons select all and deselect all
Simply click deselct all
No matter when and in which session you do this!
NOTE: For non-selective operation Commander do not use tag. Only for selective operation tag is used.
This is because it lets user to filter their tiddlers in two stage. First one can search a bunch of tiddlers for operation
and then select among them where writing filter may be cumbersome.
