To choose a letter, move the cursor over it and pause.
If you keep moving across the letter and on to another one,
it will not be chosen. When a letter is chosen it is added to
the 'Message Area' at the top. An audible beep is also produced
to confirm your selection. The beep sound can be changed in
Browse-Configure-Sounds where there are a myriad of choices.
Choosing 'Faster' or 'Slower' near the top of the window will alter how long you need to pause before a selection will happen.
To choose a letter twice in a row (such as the two T's in letter) choose 'T' once and then move OFF the 'T' and back ONTO it.
Deletion of the last letter is done with 'Del'. 'DelWord' at the top will delete the previous word. 'Clear' will clear the entire message area.
If you choose Cmd on the right another window will pop up with many commands to choose. One of them is 'Quit' - to exit Sue Center. Another is 'Help' - for complete documentation on all aspects of Sue Center.
You can also get help by choosing Browse at the bottom and then Help.
To the left of the letter area is the 'Word List' and the 'Short Words'. Read about both of these in the 'Word List' help topic.
If you choose 'Suspend' at the bottom it will change to 'Resume'. At this point the entire main window will be suspended and will be inactive until you choose 'Resume' to activate it again. This is used for when you wish to rest and ponder without choosing anything inadvertently.
See the 'Editing' help topic for details on how to edit existing text in the message area.
Normally letters are entered in UPPER case. You can choose the 'SHIFT' command at the right hand side to toggle to 'Shift' or mixed case. The first letter after this choice will be in Upper case and the rest will be in lower case. Choose it again to enter a capital letter. Choose it twice in a row to return to UPPER case. This behavior may seem odd but it works well.
Entering "ABC" in the message area will cause "Speak" to change to "Go". Choosing "Go" will alter the order of the letters. They will be arranged around the space in the center in a special way. Letters that are used most frequently in English (like E, N, S, R, A, etc) are closer to the center space than the least frequently used: Q, X, Z. This arrangement can be quickly learned and will reduce the distance the cursor needs to travel. To restore the alphabetic sort enter "ABC" and choose "Go" again.
