One of the very few areas of annoyance in Sublime Text comes when I have to do a complicated multi-select operation on a document. I hold down Cmd and start clicking through my document to create the necessary insertion points, but if I make a mistake I have to start all over again. It would be great if I could click again in the exact position of the mistake to undo that insertion point.

Ctrl+U undoes the last selection change.

Holding Alt while performing a selection subtracts that region from the actual selection.

I have found the PowerCursors package to be quite helpful managing those complicated selections: packagecontrol.io/packages/PowerCursors

Thanks FichteFoll, a couple of great tips there that will certainly do the job for me.

Robwala - that package looks cool but I don’t do complex enough selections to need it thanks.
