Editing sessions

Inside input fields of sessions, the cursor keys have a special meaning: when moving upwards or downwards, you will move to previous or subsequent input fields. When moving to the left or to the right, you will never leave the input field; you should rather use the mouse for this.

Some facilities for editing input, output and text fields are available in the Session→Insert fields and Session→Remove fields menus. Most operations directly apply to matching input/output fields. Optionally, an additional explanatory text field can be associated to an input field using Session→Insert fields→Insert text field. Keyboard shortcuts for inserting fields are A-up (insert above) and A-down. Keyboard shortcuts for removing matching text/input/output fields are A-backspace (remove backwards) and A-delete (remove current fields).

It is possible to create “subsessions” using Session→Insert fields→Fold input field or A-right. In that case, the current text/input/output field becomes the body of an unfolded subsession. Such a subsession consists of an explanatory text together with a sequence of text/input/output fields. Subsessions can be folded and unfolded using M-A-up resp. M-A-down. Subsessions have a nice rendering on the screen when using the varsession package in Document→Use package→Program.

Other useful editing operations for text/input/output fields are Session→Remove fields→Remove all output fields, which is useful for creating a demo sessions which will be executed later on, and Session→Split session, which can be used for splitting a session into parts for inclusion into a paper.
