What does Alt + L do?

[cocoscacao]

Since I'm using lazy orbits mod to test freaky stuff in... orbit... I've pressed Alt + L accidentally instead of Alt + H to bring up mod's interface. However, pressing Alt + L  is doing something in the background. There's a "turn on/off" sound whenever those keys are pressed. But I can't figure out what they do. Any info?

Prevents staging, I believe.

@Vanamonde Either that's not the case, or I'm doing something wrong...

Not sure about KSP 2, but in KSP 1, Alt+L toggles the staging lock as indicated by the green/purple LED on the staging display. When enabled, pressing space will not activate the next stage, think of it like having a safety cover over the big red button.

In KSP 2 it might do something else, or staging lock might be broken in KSP 2, if so, submit a bug report.

I'll double check it again first
