I love the tips that IntelliJ IDEA gives you. I often hover over some bad code, waiting for the lightbulb to show up on the left hand side.
Sometimes, it doesn’t quite show up. Other times, it shows and sneaks away as my mouse gets near.
I got to get good at coaxing the lightbulb out of its shell. I sneak my mouse up to the code in question and surprise the underlined area, teasing the bulb.
Then I realised that I could just hit ALT + ENTER and the lightbulb now has to listen to my every whim.
