Shift-F2 zoom was present in the earliest versions of MS-Access, and is still there to this day. Editing a cell or field with a long text string becomes difficult, tedious and error-prone if you can only see a few lines at a time. This is an issue in long database fields, in spreadsheets, in web forms. The terrific solution that MS-Access implemented was Shift-F2, in order to zoom the field into a much bigger editing box. I use it all the time in Access.
20 years later, and nobody seems to have copied this feature. I frequently fill in forms and edit cells that don't have enough real estate to view the entirety of a paragraph or two of text.
