i hit the same things on mac, like ctrl-a/e.
couldn't jump to the beginning and the end of the file either.
i tried various shift key combinations until i finally inserted some special character which i couldn't delete.
all this happened within ~20seconds of trying it.
not sure what to conclude from it; im still in shock.
somehow the language of announcement is not in line with the capabilities of the tool. it suggested something more mature.
Missing standard text editor behavior that I know of:
- right-clicking on selected text
- dragging-and-dropping selected text
- triple-click to select paragraph
- OS X emacs keybindings: ctrl+n/p/f/b as arrow keys, ctrl+a/e to go to beginning/end of line, ctrl+k/y to cut/paste, etc
