Request: sounds, "hitting" players, changing gamemode using /commands

Sounds..to wakeup players
I am not after playing custom sounds.
It would be enough to "wake" players up to let them watch the chat
A jingle played using the piano sounds would be awesome.
Like "Tadaaaa.." Server restart is imminent

Punching players.. to wake them up
Like hitting them using scripts to produce the punch "ouch" sound.
Even the moaning stomach will be fine to get their attention
Question.. what would be the proper command to produce an "impact" on a given player?

SETGAMETYPE changes of other players without being able to open the console
Some players reported they were unable to open the console(for using setgametype 1).
Must be strange laptops.. -.-

Even with hints like \ or PIPE+\ or those key below the ESC key.. nothing helped.
Is there a command in lua like target.player.setgamemode=1 or so?
Then i could add a command like /sgm <player> 1 ..

Even better.. if the wiki would be accessible to all of us.. and if there would be a link to all the possible "lua-commands" like get.player.pos (or whatever).

Yes, if I was one of those poor people(with special keyboards -.-) I would get a "spare" keyboard attached.. and even if it is for just this one purpose

But nevertheless.. some people would like to use the creative mode.. and if they are dum* err.. not able to find the proper keystrokes on their machines..
I would really like to use a "straight" command to change their gamemode for them.
If i found a solution using scripts(have FINALLY found a 0.5.3 API ) I will show it up here.

Well, then some of them gathered on my server, btw. they are great in building nice stuff.. but technically using the console seems to be too complicated for SOME of them.
On the other hand.. i am really not able to build nice houses like them

[edit] added the bolded text..

Thank you yahgiggle for your kind words but that was not due to talent, that was luck or coincidence to get some things working while experimenting with those lua script files..

Maybe my "wish" for this command does not seems of any practically use for you now but I am still looking

Quote from red51

Sounds which are callable from the scripting API are planned In the future, it's also our intention to play custom sounds.

Basically the same as the "slap" function in the rcon tool? Maybe that's not a bad idea, we will add it

Currently that's unfortunately not possible, but also on our todo list^^

Custom sounds
If we someday would be able to add new.. tools the addition of server side sounds.. would be nice(not easy to implement as the sound file has to be transmitted to the clients..)
For the moment I would be very pleased if we could get access to play sounds(already given in the game, serverside) at the targeted player position.

SLAP command
Thank you, you really saved my day!
(I knew I had used this command SOMEWHERE but I was unable to remember where. Im not insane, at least not YET )

changing gamemode ingame
Again thank you.. i was just looking around in the code to find something to get this done..
Your information stops me spending time
