If you've added text to your FormSketch map, and would like to edit it, you can do this simply by selecting the Arrow tool, and then selecting the text you would like to edit. It will appear to have a box around it, which you can use to increase or decrease the size of the text as well as move it around the map.
If you tap / click on the text a second time (while it has the box around it), then a typing cursor will appear among the text, and you will then be able to edit what it says. You can simply click / tap somewhere else in the map once finished.
