- Can into scope too!
- Especially useful and underused: Have IDEA open new tabs for each search (default is replace last search)
- All platforms: ⌥[F7]
- Probably most used is rename (⇧[F6]): highly consistent!
- Also works for files, change lists, packages…
- Extract variable, field, method, constant… loves expand selection
- Underused: Change Signature (:apple:: ⌘[F6] // :penguin:&:door:: Ctrl + [F6])
- also very consistent! Works e.g. for DB Tables Schema
- Check out what’s available available inspections
- Can integrate some external tools!
- A lot support quick fixes; underused: “fix all … in file”
- When “fixing” a warning results in worse code, just disable the occurrence!
- Depending on situation “with comment” + append reasoning
- Really important to stay at 0 warnings: “Broken window code policing”
* + ⇥
* <expr + . + abbreviation> + ⇥
NTH, but a crapshoot
- E.g. Oracle, PostgreSQL, Groovy, XML, HQL, HTML, CSS, …
- Also as Annotations – check Settings
- Checked-in documentation that triggers IDE magic!
Everybody uses ⏎ to insert the completion, but there’s also:
