PowerTab extends the tab expansion feature of PowerShell to offer more productivity for PowerShell users.
Tab expansion is a productivity feature of PowerShell similar to intellisense. Pressing the TAB key will cause PowerTab to suggest full paths, command names or values based on the current context of the cursor.
