Change the Animation speed in After Effect

Hey Guys
Just need quick help and suggestion from video experts .I have Been using after effects for sometime .The issue i am facing is with the video and animations.The text animations are bit fast and i want to slow it down it has low of texts and almost 12 slides with text .I searched a bit and found key frame thing can change the animation speed.But in my case i didn't found key frames options or there could be something that i am missing.
Now what i want is either i could slow down the texts somehow or able to slow down the video.I Think if i could change the frames of video it could slow down the animation a bit although i am not sure.Any help or suggestions would be great.

Thanks.

If you still need to know, here's how.
You can slow down the comp by right clicking "Enable time remapping". Press U to display keyframes and drag the comp longer.
The correct way to do this would simply be to move the keyframes of the text and/or camera. Similarly, press U on the layers to see the keyframes. Drag accordingly.

Yes, ChrisX is totally right.. Time Remapping would be good option..if you want to change the speed of the whole animation. (making duration of the comp longer..= time remapping), so to do this... you'll need to get all the animation comp.. in to a new comp, .. or you can Pre-compose all layers of current comp (CTRL + Shift + C)....and then add time remapping.
** to do the Time remapping --> Right click on the comp and go to Time -> Time Remapping

Click the 'enable time mapping' and drag it from there.
