> To name one: You realize after finishing your code block that the first two lines of it actually shouldn't have been part of the code block, but should have been normal text above.

    * move the cursor to 0,0
    * hold shift and hit down-arrow twice to highlight the first two lines
    * continue holding shift and hit left-arrow once to deselect the EOL on the second line
    * use the keyboard shortcut for toggling code blocks (cmd-alt-shift-c)

awkward, but it works. :shrug:

EDIT: formatting
