  <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.

  <\example>
    Below, you will find the <hlink|previous example
    session|man-session-edit.en.tm#session-example>, but now using
    mathematical input:
