Re: Lpex Editor - Ctl-A and Delete & Ctl-V

LPEX has four selection (block) modes. Enter
?selection
on an LPEX command line, then select "Changing the default marking mode" for details.

Normally you set the selection explicitly (Alt+R RECTANGLE, Alt+L ELEMENT, etc.). In other cases (e.g., mouse-drag selection) the default selection type (= editor parameter block.defaultType) is used, which can be set via the Window > Preferences > LPEX Editor > Block preference page. In other cases, like Ctrl+A, a specific type may be enforced because of one reason or another...

Ctrl+A does a CHARACTER (rather than a STREAM) selection because LPEX keeps the cursor inside the visible view at all times (when you scroll, the cursor moves to stay on a line inside the screen). If Ctrl+A were to do a stream selection, then 1.- the cursor would have to be set at the end of the document, 2.- any scroll the user would do at that point (e.g., mouse clicking or dragging on the scroll bar) will cause the cursor to move and consequently clear the selection...

You can always delete the entire selection with Alt+D or pop-up menu > Selected > Delete selection.

Joe's suggestion - Ctrl+Home, Ctrl+Shift+End - is another good alternative.

Thanks for this explanation, Adrian. I never considered the difference between character and stream selection; now I understand this side effect. What determines which selections are character vs. stream? I'm guessing that the Alt-R is a character selection, for example.
