I'm relatively new to IDEA and I don't know all the tricks and ins-and-outs of it yet, so sorry if this feature already exists, or if it's a really easy question to answer...
Is there a way to tell IDEA "Hey, I want you to re-index this module (or directory, or file) right now, please." In general, IDEA seems to be pretty good at staying on top of changes, but I've noticed a few times where IDEA's UI hasn't caught up to changes I've made (for example, if I remove a needed module dependency, I frequently have to actually open up .java files in the viewer before IDEA will re-index them and flag them as having an error.
Furthermore, a "Hey IDEA, stop indexing right now, I just want to read this damn file" button would be nice too, but I'm sure there are a bunch of reasons over my head for why that would be a terrible idea.
I'm sure I'm not the first person to think of this, and I bet it has been discussed before (I didn't find any threads in my cursory search, feel free to flame if I missed something obvious), so I imagine there's a good reason the feature doesn't seem to exist... I am just curious what it is.
