don't save in Repl, clear Repl on ALT+A
default mod key now CTRL, added useSuperKey to setup() to enable Super as mod key & added isModifierPressed, open file is now MOD + O & toggle show/hide is now MOD + T to avoid clashes with CMD on OSX; added open/save events, renamed loadFile to openFile to match MOD+O better; fixed Repl console logger bug where log header was being stripped before stdout
clear filename when clearing editor
