This happens a lot...
OpenVSP is a tool best learned (for many of us) through a discovery process. "What does this do? -- click, drag, poke, observe -- Oh, that is what it does."
Unfortunately, it is not always obvious when things can be tried -- in particular something like a hot-key where there is not an immediate visual cue.
Brandon has been working hard on our documentation -- mostly as videos, per user requests -- but there are a lot of us who never consult the documentation. I don't just mean for OpenVSP -- it is very rare that I ever consult a software program's documentation. I have the expectation that I will be able to figure out whatever I need through discovery. Usually that works, but sometimes it is inadequate.
I like to believe there aren't a lot of "hidden magic" features out there that users like you could be missing -- but I could easily be missing some.
Do you know that you can drag-n-drop Parm's to most GUI's where you might need to specify a Parm?
