# Tab Complete! It's sad and amazing how few people rely on tab completion, both in the PowerShell ISE and in the console window. * When you tab complete, you'll never spell commands or parameter names wrong * For many parameter values that are static lists, or easily-queried lists, tab completion (especially in v3 and later) can fill-in legal parameter values for you * Tab completion makes long cmdlet names a lot easier to type, without the need for difficult-to-remember aliases. Get into the habit of using tab completion all the time, and you're guaranteed to make fewer mistakes. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
