This tool renames lines to a,b,c, points to A,B,C and angles to \a,\b,\c with mouse clicks using this tool. The first unused letter will be used.
Force A, B, C by pressing the shift key when you click on a point. Letters will then be switched, if they were already in the construction. To start over, press Escape.
By the way, if you need the letter "a" for two different objects, use "a~1" and "a~2". Names show only up to "~". Alternatively, use an alias.
