Roam on Chromebook - Add shortcut keys for moving blocks up and down in outline

Roam-UpDownBlocksShortcuts-Chromebook

// Enable the Move block up and down from keyboard on a Chromebook
// Use CTRL+ALT+K (move block up) and CTRL+ALT+J (move block down)

// This code is dependent on Roam42, thus the 10 second delay to 
// allow roam and roam42 to initiialize key assignments can easily 
// be changed. See the Mousetrap documentation for key support:
// https://craig.is/killing/mice

// ADD TO ROAM
// 1) Create new page & name it something you will remember
// 2) In empty block type {{[[roam/js]]}}
// 3) Create a block under that one, indent it (tab key)
// 4) Create /Code Block. A new code field appears
// 5) Copy code from below into the code field
// 6) Click Yes, I know what I am doing button
