Text Tokens vs. Identifiers
Ordinarily the MathFlow editor assumes alphabetic characters are identifiers. Sometimes, however, you may want to treat a run of alphabetic characters and spaces as text. In particular, if you are entering a bit of descriptive text in an equation, you will want the space bar to insert spaces, not InvisibleTimes characters. You can tell the MathFlow Editor to treat a run of characters as text by inserting a text template from the toolbar.

When you insert a text template, the editor assumes subsequent alphabetic characters and spaces should be treated as text, and won't break them into smaller tokens.
To switch out of a text token to an identifier token, either move the cursor to the right until it loses its I-beam shape, or press the Tab key.
