Using the PowerShell Command Line:
PowerShell has some very basic line-editing capabilities that you can use when typing at the command-line. These are not substitutes for a full development environment if you're writing scripts or cmdlets, but they provide basic features when you just need to run a script or cmdlet interactively such as:
Down- and Up-Arrow displays previously entered commands.
Left- and Right-Arrow move the cursor left and right, respectively.
Home key moves to the beginning of the current command.
End key moves to the end of the current command.
Ctrl+Left and Ctrl+Right jump one word to the left and right.
Insert toggles insert/overwrite mode.
Backspace deletes the character in to the left your cursor.
Delete removes the character to the right of your cursor.
Press Tab to auto-complete path names and object members.
Esc (escape) clears the entire command-line so you can start over.
