Direct Keyboard Access to Brushes

From ZBrush Info

Because of the large number of new brushes, a new system using the alphabet and associated shortcuts has been added.

At the top of the floating brush palette, click on the letter of your choice to display only the brushes starting with this letter, such as “C” to display all the Clay brushes and the Crumple brush.

You can also use the keyboard shortcuts to access to these brushes in half a second:

• Press “B” to open the brush window
• Next press the first letter of your choice, like “C”. All the brushes starting with “C” will be displayed. If you hit a wrong key, press the space bar to go back to the default brush window.
• Notice at the top left of each brush icon, an orange letter appears: press it to choose this brush, like “T” for Clay Tubes.

The Clay Tubes brush is now selected.

Then, by pressing keystrokes like B,C,T, you will be able to pick the brush that you want in an efficient way.
