Memory Lock
Qedit has commands for enabling and disabling the terminal Memory Lock. This is so that you can leave the User Keys displayed on your terminal and still access the Memory Lock function:
/$
{or $+enables memory lock}
/$-
{disables memory lock}
To use memory lock when prompted for a command, just move the cursor up to the desired line, type "$" and hit Return. This feature does not work in Visual mode.
