If I print off text, laminate and use a hole punch, I can attach a self made label to a cable, handy to quickly id, as for some reason, most cables are black, so when one has a PC with Power, Vga or HMDI, keyboard, mouse being able to quickly id each is a pain.
Oddly we used to have coloured ends to plug in, so purple IIRC was erm keyboard, now why can't we standardise on a single colour for a set use, so keyboards all have the same colour cable (regardless of who makes them) that could make life a LOT easier.
