IntelliJ cheat sheet

My cheat sheet of IntelliJ (and PyCharm) shortcuts.

Initial setup

• Open settings: Control + Alt + s or cmd + ,

• Disable spell checking:

  • Filter by "spell", and then: Inspections / Spelling / Typo

• Ensure line feed at file end:

  • Filter by "end of line", and then: Editor / Ensure line feed at file end on Save

• Jump to high priority errors first:

  • Filter by "next error", and then: Editor / 'Next Error' action goes to high priority problems only

• Show line numbers:

  • Filter by: "line num", and then: Editor / Appearance / Show line numbers

sout        insert System.out.println()
iter        insert for-each iterator to iterate over an iterable in the current scope
