The basic rules for using a mouse in an Open Look application such as WAVE are:
Notice boxes and some other windows have default buttons, identified by a double oval outline. If the pointer is anywhere in the window, you can press \Ovalbox{\small\sf Enter} ( \Ovalbox{\small\sf Return}) instead of clicking left on the default button if you wish.
To type into a text field, move the mouse pointer near the insertion point and click left. The text cursor should appear nearby; if it is a black triangle, you may begin typing. Use \Ovalbox{\small\sf BackSpace} or \Ovalbox{\small\sf Delete} to erase the character to the left of the text cursor. To move the cursor within the field use the arrow keys ( \Ovalbox{\small\sf $\leftarrow$}, \Ovalbox{\small\sf $\rightarrow$}), or use emacs-style commands:
Until you press \Ovalbox{\small\sf Return} (or \Ovalbox{\small\sf Enter}), your typing is not interpreted.
Unless spot help is disabled, you can get help on any control by pointing to it and pressing \Ovalbox{\small\sf Help} (or \Ovalbox{\small\sf F1} if you don't have a \Ovalbox{\small\sf Help} key). To enable spot help, see ``How do I get spot help ...?''.
