The first thing you probably want to know is how you're going to remember all the stuff in this document! After you use Rune for a while, these commands will be second nature, but until then, you can get in-editor help by pressing the ? or / key. Note that if you are in edit mode (see below), pressing this key will simply insert a ? or / character, and you will have to leave edit mode to see the help screen.
If you create a new file in the MOSS operating system, Rune will launch and greet you with a blank document.
You can simply start typing to enter text. The backspace key, return key, and shift will all work as you'd expect in other operating systems.
However, certain keys will not have the effect you're used to: the arrow keys, caps lock, and control/command/meta/alt keys have no effect in Rune.
g goes to the end of the current line; a goes to the beginning. Shift-g and shift-a select.
f and t work as in Vim. shift-F and shift-T select in addition to moving.
s works like Vim's /.
... If the selection is not empty when you enter insert mode, the selected text is deleted and moved to the kill ring.
You can copy the selected text by pressing c.
v brings up the paste menu, which shows all the snippets that have been copied to the kill ring. The kill ring is stored on disk, so if you copy in one buffer you can paste in another. Rune remembers your copy history even after you reboot the computer!
If you're sure of what you last copied, shift-V simply pastes the most recent item from the history.
If you press delete, the "Semicolon" banner disappears—it's as if you never pressed the semicolon key in the first place.
