When naming buttons, name the action that
the button will trigger, especially if it is potentially destructive.
For example, in a warning message dialog box, Delete All and Cancel buttons are clearer than OK and Cancel buttons.
Use title capitalization for button names, such
as Clone or Run Report. Don’t use
ending punctuation in button labels.
Don’t use any special formatting when referring
to buttons.
Documentation
Use bold text when referring to buttons: Click Save.
Use the name of the button exactly as it appears on screen.
Don’t list the following UI element
types unless needed for clarity or navigation: button, checkbox, drop-down
button, field, icon, menu, link, radio button, or window. For example,
write Click Save, not Click the Save button.
