Scratch

For horizontal movement:

when (green flag) clicked
forever
   if <key [left arrow] pressed>
     change xvelocity by -0.5
   if <key [right arrow] pressed>
     change xvelocity by 0.5
   change x by xvelocity

Hope that helps

there are plenty of velocities, here are the 2 most important:

moving technique:
forever
if <key[left arrow]pressed?>
   change Xspeed by (-0.2)
if <key[right arrow]pressed?>
   change Xspeed by (0.2)
if < <not<key[right arrow]pressed?> > or <not<key[left arrow]pressed?> > >
   set Xspeed to ( (Xspeed) * (0.9) )
change X by Xspeed

jumping technique:
forever
if <key[up arrow]pressed?>
   set Yspeed to (5)
   change Y by (Yspeed)
   repeat until <touching color [ground color]>
      change Y by Yspeed
      change Yspeed by (-0.2)
   set Yspeed to (0)
