You're completely wrong bearodactyl ;) There is no comanglia config being used, afaik it's closer to chris' high quality if config at all!
Player switching binds are not hud dependent, they are built into CastingEssentials and can be set up like this:
alias blu_scout "ce_cameratools_spec_class blu scout" // Cycle through all blu scouts
alias blu_scout1 "ce_cameratools_spec_class blu scout 0" // First blu scout in the hud
alias blu_scout2 "ce_cameratools_spec_class blu scout 1" // Second blu scout in the hud
bind 1 blu_scout1
bind 2 blu_scout2
Of course you can change the class to soldier/pyro/demo(man)/heavy(weapons)/engie(neer)/medic/sniper/spy and create your own binds or aliases.
