<tmdoc-title|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 <menu|Session|Field> menu. Keyboard shortcuts for inserting fields are
|
|
<shortcut|(structured-insert-up)> (insert above) and
|
|
<shortcut|(structured-insert-down)>. Keyboard shortcuts for removing
|
|
matching text/input/output fields are <shortcut|(structured-remove-left)>
|
|
(remove backwards) and <shortcut|(structured-remove-right)> (remove current
|
|
fields).
|
|
|
|
It is possible to create ``subsessions'' using <menu|Session|Session|Create
|
|
subsession> or <shortcut|(structured-insert-right)>. In that case, the
|
|
current input-output field becomes the body of an unfolded subsession. Such
|
|
a subsession consists of an explanatory text together with the subsession
|
|
body. Subsessions can be folded and unfolded using
|
|
<shortcut|(dynamic-previous)> <abbr|resp.> <shortcut|(dynamic-next)>.
|
|
Subsessions have a nice rendering on the screen when using the
|
|
<tmpackage|framed-session> package in <menu|Document|Use package|Program>.
|
|
|
|
Notice that input/output fields and subsessions are foldable: when clicking
|
|
on the prompt with the mouse, you may fold or unfold the entry to hide or
|
|
show the output. For laptop presentations, this folding and unfolding
|
|
process is done automatically when traversing your presentation. It is also
|
|
possible to fold or unfold all fields in a session using
|
|
<menu|Session|Session|Fold all fields> and <menu|Session|Session|Unfold all
|
|
fields>.
|
|
|
|
Other useful editing operations are <menu|Session|Session|Clear all
|
|
fields>, which is useful for creating a demo session which will be executed
|
|
later on, and <menu|Session|Split session>, which can be used for splitting
|
|
a session into parts for inclusion into a paper.

<\example>
|
|
<label|session-example>A typical <name|Maxima> session is given below. If
|
|
<name|Maxima> is present on your system, then you may put your cursor in
|
|
one of the inputs, perform some edits, and try to reexecute it.
