The Status Bar

The Status Bar is located at the bottom left-corner of the screen and can be used for the following purposes:

to display brief information relating to a specific icon or menu item
to show the progress of commands
to display/set the position of the mouse in XYZ space in the currently open file
to display if a command is currently running
to show the read status of the currently open file
to see/set numlock, scroll lock and caps lock statuses.
to view the viewplane distance between subsequent mouse clicks.
to view the current azimuth and dip values of the last clicked point.
to pick a custom cursor for use in the primary 3D window.

The Status Bar is available in all windows.

More detailed information on some of the Status Bar zones:

Messages

This read-only area displays prompt information when running commands, and provides information about the menu item or icon directly under the cursor (for icons, a tooltip will also be displayed).
Cursor Position

The XYZ location of the cursor is updated dynamically with mouse movement. Note that the Z value will normally remain fixed for mouse movement in the Design window as the view is in a fixed plane. In the Plots and Logs window, as these are 2D viewports, no Z value will be displayed. In the Visualizer, Tables and Reports windows, this area of the status bar is inactive.
Cursor Appearance

You can see the cursor that is currently in use in the primary 3D window here. By default, this is set to <none>, meaning a default cursor will be displayed. Double-clicking this section of the Status bar displays the Custom Cursors dialog, from which you can select an existing custom cursor or design one. More...
Quick Key Status

This area displays information relating to a recent quick key command. The information displayed will show the key combination, and the name of the command. If a key combination is typed that isn't recognised, the command name will be shown as 'ambiguous'.
Snap Mode Status

The current snap mode is also displayed in the status bar. You can see if your Snap Mode is set to [GRID], [LINES], [NONE], [POINTS] or [SURFACE]. Double-clicking this part of the status bar displays the Snap to Mode dialog.

You can also view useful context-sensitive information using your application's Cursor Messaging System. More...
