I often paste a function on the App or Server console, for example something like this one.
Pressing up arrow after executing a multiline command like the definition of a function, puts the whole function in the current line (good).
Pressing up arrow again goes up one line in the multiline command (good).
There is no way to go to the previous command on the history, other than pressing up arrow many times (bad).
Please add one shortcut, for example Ctrl+Up or PgUp, to skip to the previous command without stepping through each line of the current command.
