<tmdoc-title|Selecting the input method>
|
|
|
|
By default, <TeXmacs> will attempt to evaluate the input field when
|
|
pressing <key|return>. Multiline input can be created using <key|S-return>.
|
|
Alternatively, when selecting the multiline input mode using
|
|
<menu|Session|Input mode|Multiline input>, the <key|return> key will behave
|
|
as usual and <key|S-return> may be used in order to evaluate the input
|
|
field. Notice finally that certain systems admit built-in heuristics for
|
|
testing whether the input has been completed; if not, then the <key|return>
|
|
may behave as usual.
|
|
|
|
Certain applications allow you to type the mathematical input in a
|
|
graphical, two dimensional form. This feature can be used by selecting
|
|
<menu|Session|Input mode|Mathematical input>. If this feature is available,
|
|
then it is usually also possible to copy and paste output back into the
|
|
input. However, it depends on the particular application how well this
|
|
works. Keep in mind that some key combinations may be used by the
|
|
<subsubmenu|Session|Input|Mathematical input> mode: for instance the key
|
|
<key|$> is usually redefined inside math mode, so if you want to input it
|
|
you'll have to type <key|S-F5><key|$>. You can read more about the prefix
|
|
key <key|S-F5> in \P<hlink|Keyboard shortcuts for text
|
|
mode|../text/keyboard/man-text-kbd.en.tm>\Q.
