- APPENDIX I
- EDITING INPUT PROMPTS
-
- You will notice Vocal-Eyes has several input prompts. This is where you are
- required to type specific information. Examples of input prompts would be a
- file name, find string, speech rate, window coordinates, window to switch to,
- etc.
-
- If the prompt is only asking for a single character, you can simply press the
- character and that is that. However, our emphasis here is for those prompts
- which require more then one character. In our above examples of input
- prompts, window to switch to requires only a single key 0-9. However, all
- the others could require two or more keys.
-
- As a simple example, enter review mode and press F for find. When Vocal-Eyes
- says "Enter pattern to find," type in "Mary had a little lamb" but do not
- press ENTER. Oops, Mary did not have a lamb, she had a tiger. Well, press
- the BACKSPACE character until you hear the "l" of lamb. The backspace key
- will erase each character that it backs up on. Now type "tiger". Oops, Mary
- doesn't have a tiger, Barb does. So press the left arrow until you hear the
- M of mary. Unlike the backspace, the left arrow only moves the cursor but
- leaves all existing text alone. Once the cursor is on the M of mary type
- "Barb". Now press ENTER. even though your cursor was after the b of Barb,
- the entire line "Barb had a little tiger" was accepted. Of course Vocal-Eyes
- beeped at us because it could not find this string on the screen. That's ok,
- we are not really interested in finding text anyway.
-
- Now press F once again. Notice, Vocal-Eyes remembered what we last typed?
- This is called the default. If the default is what you want simply press the
- ENTER key. The entire string will remain as it is. However, if you start
- typing something new, Vocal-Eyes will clear the entire default and allow you
- to type from scratch. For example, type "test". Those of you that can see
- will notice as soon as the t of test was typed, the entire default string
- disappeared. Now your string is simply "test". If you were to press ENTER
- now, this would become the default string. However, what if you made a
- mistake and wanted the previous string back? Well, if you press the ESCAPE
- key, Vocal-Eyes will abort the current setting and forget all your changes.
- Go ahead and press ESCAPE now. Notice Vocal-Eyes did not beep because it did
- not try to find anything. You aborted the find. Now press F again. Notice
- the previous default came back. Now what if you want to change "tiger" back
- to "lamb"? Well, you could retype the entire line or you can press the right
- arrow until you are on the t of tiger. Go ahead an try this now. Notice,
- your default did not simply disappear like before? If your very first
- keystroke is a right arrow, Vocal-Eyes will not clear the default. If you
- type any printable character, it will. Now that you are on the t, type
- "lamb" and press ENTER again.
-
- Press F again. Notice our string is not what we wanted? The word lamb is
- spelled "lambr". The r is left over from the word tiger. Remember, no
- matter where your cursor is, Vocal-Eyes will accept the entire string. Okay,
- we are not sure what Barb has so let's only search for the string "Barb had
- a". So press the right arrow until you are on the space after the a. What
- would happen if you press ENTER now? That's right, Vocal-Eyes will accept
- the entire string. So how about pressing ALT-E? Vocal-Eyes will erase all
- characters under and to the right of the cursor. Now press enter and the
- string will be "Barb had a" exactly what we wanted.
-
- Now, one last example. Press F to get the default string "Barb had a". What
- if we wanted to change the name from "Barb" to "Tim"? How about simply
- retyping it? Well, remember as soon as you type the T of Tim, the entire
- string will disappear. This would cause you to retype the entire entry. You
- could do that but remember, we are trying to make a point here. So, instead
- of pressing T, start by pressing the right arrow. Therefore, Vocal-Eyes will
- not clear the string. However, we are not on the B of Barb. To fix this,
- press the left arrow. This defeated Vocal-Eyes' clear default feature since
- you started with a right arrow. Now simply type "Tim". Fear not the rest of
- the string is still intact. In fact, too much of it. We still have the b of
- barb left over. You can verify this by pressing the arrow keys. Make sure
- the cursor is on the unwanted b and press the DELETE key. Vocal-Eyes has
- removed the character and pulled all characters to the right one position to
- the left. Our string is now "Tim had a", exactly what we want.
-
- Although this entire example was done using the Find string, the exact same
- can be used for all the other prompts including the speech rates, volume and
- even file names. Feel free to practice using these editing commands. We are
- sure these features will save you keystrokes from time to time.
