# 3.2. Progress indicator and management

The left section of the status bar contains a progress indicator. This indicator is used to inform the user what is taking place for certain operations. It displays the kind of operation by printing a text string in the bar (eg, `reading...`) and a progress value.

Any operation that uses the indicator can be interrupted by the user. This is done by one of the following operations:

- Pressing (any mouse button) on the progress bar.

- Clicking on the "`Cancel Operation`" toolbar button.

- Selecting the "`Cancel Operation`" entry in the `File` menu.

The user will then be prompted to confirm the cancellation.
