Hi.
Do you mean that you want the field to "become" empty when you press spacebar? That is easy.
But what do you mean by "the last" or "the next" command?

Hi Craig,
But what do you mean by "the last" or "the next" command?
I think expected behavior is same of messages box.

Shalu.
So is Jean-Marc correct? You want this field to work like the message box? Interesting challenge if so, but please confirm.

OK. I did this in two handlers for readability. You need to pay me by rewriting in a single handler. Now which message should you use?
In a field script:
Code: Select all
on keyDown tkey
put tKey after me
set the lastText of me to me
if tkey is space then put "" into me
end keyDown
on rawKeyDown tKey
if tKey = 65362 then set the text of me to the lastText of me
select after text of me
pass rawKeyDown
end rawKeyDown
Get going.

Shalu.
I have seen your video, but I do not understand it.
But is this what you wanted":
Code: Select all
on keyDown tkey
put tKey after me
set the lastText of me to the lastText of me & tKey
if tkey is space then put "" into me
end keyDown
on rawKeyDown tKey
if tKey = 65362 then set the text of me to the lastText of me
select after last char of me
pass rawKeyDown
end rawKeyDown

@dunbarx sorry for the late reply
It's ok now but the problem is when I press up arrow tex field is display the all last entered words. suppose the last entered words are word1, word2, word3 (word1 space word2 space e.t.c). If I press up arrow then word3 should display and If I again press uparrow then word2 should display. now the current output is word1 word2 word3

Hmmm.
Are you saying you want to store each field entry separately when you hit the spacebar? That is, each time the field is cleared? And then recall those entries one-by-one when you hit the up arrow?
If so, then make a second field, a bit larger than the first. Change your field handler to this:
Code: Select all
on keyDown tkey
put tKey after me
if tkey is space then
set the lastText of me to me & return & the lastText of me
put "" into me
end if
put the lastText of me into fld 2
end keyDown
on rawKeyDown tKey
if tKey = 65362 then
--your homework here
pass rawKeyDown
end rawKeyDown
Now this will load your text snippets into both the custom property and the field so you can see it. You will want to think of a way to clear that property, I would imagine, and maybe add other required gadgetry.
@Jacque, please look the other way. OK? Good. Now, Shalu, tell me how you can, in the "rawKeyDown" handler, extract each line of the custom property, one by one. This is tricky, but should be fun.
@Jacque! I asked you to turn around please.
