The toolbar is displayed across the top of the application window, below the menu bar. The toolbar provides quick mouse access to many tools used in PC1D.
To hide or display the Toolbar, choose Toolbar from the View menu (ALT, V, T).
For help on the use of a particular toolbar button, select the button at the far right edge of the toolbar, displaying a question mark and an arrow. The cursor will change to match this button. Point the new cursor to the button in question and press the mouse key. A Help file will open on-screen with information about the purpose of that button.
