5 specific Questions or request on the Video recording

Hi all, Hi 'Heroes'! Sorry for I cannot modify this title: 1 question here only

Screencasting my videos with SL, I might not have found the proper manipulations in SL...or might need to enter a request? I would really appreciate your help …

• how can I have the 'typing text' effect during my recording?

i want to have the learner to see the text being typed inthe field, letter by letter, or a movement , and not the complete text to appear? Can this be done?

•  Can we also manage the lenght of this text typing?
• if not...should I enter a request....?

 Many thanks for any help and special thanks to Ant. P. for proofreading my post ;O)
