Sus2 chords
Sus2 chords are formed with the second note in the chord lowered one step. In addition to sus2 there is sus4, that is some more common. If you see instructions to play a chord as Esus or Asus it's usually not sus2 but sus4 chords. Sus2 is also often played exactly as add2 chords.
The shift from the original major chord to the sus chord is sometimes easily done. Below you can see that the difference from a major chord to its "sus2 version" is small:
C major Csus2
There are two differences: 1) on the fourth string the tone is lowered one step from E to D, 2) you don't play the highest open string because this is an E note. When shifting from C to Csus2 you only need to lift the long finger and you don't move the rest of the fingers.
