I said random because I want to know global solution but I had in mind particular applications like text editor or file browser. What about when I want to edit some file which require root. I don't want to open tiny root (or filecase root ) and then search particular file instead just type tinyedit dirty.txt.
I know there is vim (or similars) but it doesn't works correct with my keyboard mapping and fingerterm. Anyway reading big files is nicer with gui.
