Auto-Enter ?

Mind is blanking on this one, but is there a way to have an a "auto-enter" in a read command? I ask because I am revamping an old script I had written for someone, and one of the features is to browse through your contacts. Its is a pain to hit F to go forward and B to go backwards.
Is there anyway for me to just hit F or B (no enter required) to do this?

Hi:
There's a way, but you have to mess with the terminal driver:
readkey() { oldstty=`stty -g` stty -icanon -echo min 1 time 0 dd bs=1 count=1 /dev/null stty $oldstty }
echo "Press a key" c=$(readkey) echo $c

Im so close I can taste it :)
The whole thing seems to do exactly what I need except for one thing, I get: dd: unknown operand /dev/null
Any thoughts?

Forgot to add. If I remove /dev/null I get: 1+0 records in 1+0 records out 1 bytes transferred in 1 secs (1 bytes/sec)
Which is the dd output, and the reason I assume /dev/null was in there.

You're looking at the output of the dd command. This forum wipes out the arrow keys upon occasion. redirect the output of the dd command to /dev/null, and it should work.
Sorry about that!

No need to be sorry, I figured as much and had tried that previously, but when I do that, I get the same output 1+0 records in 1+0 records out 1 bytes transferred in 1 secs (1 bytes/sec)
but now nothing for c (i.e it doesnt echo)

Sorry again. You need to redirect standard error, file handle 2, to /dev/null, so it's
dd bs=1 count=1 2[greater than sign]/dev/null
At that, is obtained by the dd command so it won't echo unless you echo it after the function call.
