Select and click under the Window menu for the pallet to be displayed and active. Marked with a ✓ in the Window menu when active.Text Keyboard shortcut ⌘T
The Text pallet is basically the same as the "Text" menu, except that it doesn't have "Find/replace". In general it is a more convenient way to control text attributes.
The pallet is quite simple.
Font displays the available fonts.
Size displays the available font sizes.
B I U allows you to select any mixture of Bold, Italic and Underlined text.
I.. .I. ..I allows you to specify Left Align; Centre Align; Right Align text
Tip: The text attributes (especially Font and Font Size) are saved with each drawing. So if you generally want your drawing to have (say) Helvetica Size 9 point text, then be sure to save the drawing with this selected.
