Hi Oliver,

You can use the scripting function delete_residue_range (https://www2.mrc-lmb.cam.ac.uk/Personal/pemsley/coot/web/docs/coot.html#index-delete_002dresidue_002drange-709):

delete_residue_range(imol, chain_id, start_res, stop_res)

Maybe not exactly what you want, but that works fine for this purpose (*). You can give a residue range outside what you have, just to make sure everything is deleted, i.e. delete_residue_range(0,"A", -100,100000).

(*) Incidentally it has been on my todo list for quite some time to make a delete chain (etc) function...

I often find myself needing to delete a chain (from a complex or oligomer for 
example), and I always switch the color to Jone’s Rainbow and then hunt around 
for the N- and C- termini and use delete zone, which works but is a little 
cumbersome.

Being able to click on a single atom from the desired chain to delete it would 
speed things up tremendously, for example when editing the kind of 
spaghetti-model that sometimes comes out of buccaneer or Arp/warp at low 
resolution (where there a lot of peptide fragments that need cleaning up).

Best,
Oliver.
