Scrolly let's you scroll up and down while keeping the cursor on the same line. This is great to get a quick look at the lines that are off screen without loosing your position.
The functionality is basically the same as if you were using the mouse wheel.
apm install scrollyor find it in the Packages tab under settings
alt-upscroll up one linealt-downscroll down one line
ctrl-upscroll up one linectrl-downscroll down one line
You can enable horizontal scrolling by assigning keys to your keymap:
'.workspace .editor:not(.mini)':
'alt-left': 'scrolly:left'
'alt-right': 'scrolly:right'
