Simplest screenshot process

Question

Hi,
I have read a lot of web literature about screenshots on OS X 10.6. but I did not find the missing software/process/keyboard trick.
Does anyone know a software that just let me do the 3 following steps:
1. Make a keyboard combination to make appear a crosshair to take a picture
2. Take picture
3. Name the picture (or cancel) + Enter or something like that.
The pictures goes to a predefined folder.
cmd + **** + 3 : works for steps 1, 2.  but the step 3 is missing.
All I need, is to easily add a name to a just taken picture. (I don't want to start a software, make cmd+S, select folder location, ...).
In that way, I will be able to sort all pictures by both (name, date of creation) later.

hum,
Yes, you're right:  the crosshair works with Command-shift-4 and not Command-shift-3.
but,
I don't want to run after my screenshot. I just need to be sure it's at the right place, with a name I have to write.
I found an apple script on a web site doing this: and I create mine with.
Here is the code (juste change the computer user name in the thePath to set a different folder).
set format to "jpg"
set fformat to "." & format as string
set now to (current date)
set D to day of now
set Mo to month of now as integer
set Y to year of now
set h to (time of now) div 3600
set Mi to ((time of now) mod 3600) div 60
set s to (time of now) mod 60
set momento to Y & Mo & D & "-" & h & Mi & s
set thePath to "/Users/********/Desktop/"
set info to "Tag the picture you're going to take or die"
set defAns to ""
tell me to display dialog info default answer defAns buttons {"Cancel", "Ok"} default button 2
copy the result as list to {abrev, button_pressed}
set filename to "[" & abrev & "]" & momento & fformat
set doit to do shell script ("screencapture  -i -t" & format & space & (POSIX path of thePath) & filename as string)
I get for instance a [website]2011526-1723.jpg file
or a [art]2011526-1731.jpg
With a little change, the tag can indicate a different folder destination. (Art in artFolder, website in website folder, or create if it does not exist).
Now, last problem: how to update the shortcut command-****-3 to run my script and not the native's one ?
any idea ?
