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.
