IDEs, no matter which vendor they come from, are complex things. A zillion options, keystrokes up the wazoo. Moving from one to another is like having an arm lopped off. It takes a lot of time to get comfortable. Muscle memory is a powerful thing.

For software I use a lot, I find learning in bursts works well.

On first use I have an initial explore until my brain starts to overload and then just try to get stuff done.

From then on, every so often - perhaps a month later and even a year or years later, I'll go on another exploration session to build on top of what I know.

If you've never done it, it's worth trying. It worked wonders for my vi skills many years ago!
