Sorry if I voted twice (feeble memory ), but I use Nedit since it's a feature rich, plain text editor. It runs on nearly every platform, has good mouse support, syntax highlighting, search and replace, runs or gets the result of CLI commands, recent document list,..
Give it a go, if you have not done so recently.
