  <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 ``<hlink|Keyboard shortcuts fot text
  mode|../text/keyboard/man-text-kbd.en.tm>''.

    Below, you will find the <hlink|previous example

    mathematical input:
