using PTZ Controls v0.15.4

I'm looking for instructions on saving Presets using this controller. I don't see a "save" button.

The arrows and zoom work, though sometimes they move slowly and sometimes quite rapidly. But having found a setting, how do I make it a preset?

Thanks

If you got it from here, then there will also be a Discussion tab on the page where you got it. Post this question in there.

If you got it from somewhere else, then it's suspect at best, possibly malicious, and at any rate not supported here.
