They are the same thing. A lot of these abbreviations for others. I made this list by extracting a portion of our keyword table.

@FormIsStandalone should be (and is) renamed, in that it became something of a standard around here that if the name starts with "Form" then the command runs on the specified form, as opposed to running on the current form.

I should probably take it off the list - at least for 2.0.
