Tooltips and arrows
Tooltips appear on most buttons, and arrows appear on some.
When you move the pointer over a button in any toolbar, a tooltip displays a short description of it. For example, the Pause button, which becomes active once a solve has started.

Note that some buttons are associated with a small arrow
pointing downwards, such as the Run button
, Debug button
, and Browse button
. Click that arrow to select the element
to which the button action must apply, or to access other functions.
Tooltips describe adequately the functions of the standard toolbar (Save, Save all, ...) Here, we add more detail for the:
Execution toolbar
Debug view toolbar
OPL Projects Navigator view toolbar
