A follow on from my first one.
Sound out the word with the clues:
- I can move to the right, but also shift to the left.
- Actually, I'm not quite sure now.
- Oh wait, now I've got the hang of it.
- But now I'm slaughtered.
That's got to be TAB, as in the tab key on a computer keyboard. Tab moves you to the right, but shift+tab moves you to the left.
I'm guessing this is something like ER - a noise made when not quite sure.
You've got the KNACK of it (thanks @Mnemonic).
You've been CULLed.
TAB+ER+KNACK+CULL - "Sound out the word" = TABERNACLE.
