Thanks, I had trouble with arrow keys working when I tried it a while back but I'll give it another go with the "-run {bash}" option. And the Mac autocorrected "htop" to stop.
I had to test a couple of variations before being happy because the same colors are used in all types of terminal (I use regular cmd and Bash). Sometimes one color is great in one type of terminal but is clashing with another color, for a particular use case, in the other terminal!
