for Sublime Text 2 or 3
Ever wanted to scroll horizontally in Sublime Text with your keyboard?
Well. Now you can.
Step 1 -- Go get wbond's beautifully simple Sublime Package-Control.
Step 2 -- Hit ctrl+shift+p (Windows, Linux) or cmd+shift+p (OSX), run the install package command.
Step 3 -- Search for and install Horizontal Scroll.
Step 4 -- Win and/or Profit.
Is there text running off the edge of your editor?
Is this plug-in installed?
Press alt+down. Or ctrl+alt+shift+down if you're on a Mac.
There weren't any good hotkeys left! I'm sorry!
This plug-in adds one command to Sublime Text which exposes easy-to-hotkey horizontal scrolling, and makes a guess as to how to incorporate it for you.
By default, the hotkeys to scroll right and left are, respectively, alt+down and alt+up for Windows/Linux, or ctrl+alt+shift+down and ctrl+alt+shift+up if you're on a Mac -- chosen to reflect Sublime's default scroll_lines behavior (ctrl+up/down and ctrl+alt+up/down). This, of course, can be mapped to any hotkey combination you might by want by modifying your personal Preferences -> Key Bindings - User. (And seriously, if you're on a Mac, please do.)
The command that this plug-in adds is (at most):
"command": "scroll_width", "args": {"amount": [+/-]30, "by_character": True}
If by_character is left True motion is based on the width of an em-dash, which allows this command to scale motion with your current font size. If by_character is False, scroll_width will move the screen by amount of raw pixels. I'd recommend pumping amount up to at least 150 if you're not scrolling by_character.
by_character defaults to True, by the way, so if you ever set this command up -- when, say, rebinding the Mac keys -- you can skip that argument.
amount is simply a relative indicator of how far every call to scroll_width will move the screen, with negative scrolling the screen left.
