If you just key "?"into the same command line you get the full help widow.

If you "?seu" you get the SEU profile actions and commands, plus short-cut keys and the prefix commands.


Thanks, Matt

But, the "oneSpace" is a great workaround.

Where do you find these things?

I have an unhealthy tendency to use the command line instead of a mouse or a dialogue box. After embarrassing myself with regex, I went back into the documentation to see what else I was getting wrong.

Escape to get to the command line.
F1 to summon the help / references.
Click on 'Issuing editor commands'.

There are 3 separate concepts which are related to each other but are different enough to warrant separate references:
Editor commands
Editor actions
Editor parameters

The distinction between commands and actions is that a command accepts parameters; actions don't. Which makes an action quite suitable to attach to a keyboard shortcut or mouse click :-) So 'findText', having parameters, is a command but 'join' is an action suitable to assign to say, Alt-j.

Editor Parameters are sort of like environment variables for the editor.
Many editor parameters set global behaviour, but others are more transient, and act in concert with Editor Actions. Editor parameters are retrieved with the 'query' command: 'query lines' retrieves the number of lines in the source. Setting the parameters is done with the 'set' command. Here's an interesting thing to experiment with:

Open a source member.
Position to line 1, column 1.
Escape to go to the command line.
action right
Escape to go to the editor.

The cursor should be on line 1, column 2.

Escape to go to the command line
set actionArgument 25
action right
Escape to go back to the editor.

The cursor moved right 25 times.

All of this stuff is in there to help developers write plug-ins. But they can all be used from the command line too, which weirdly enough, is one way to prototype a script I want to run.
