Ok, so I'm trying to replace a ' character with \' in a ruby string. I have working code, but it was 
*way* too painful getting there for my taste.

Take a look:

ree-1.8.7-2010.02 :001 > single_quote = "\'"
 => "'" 
ree-1.8.7-2010.02 :003 > single_quote.gsub(/'/, "\\\'")
 => "" 
ree-1.8.7-2010.02 :004 > single_quote.gsub(/'/) {|c| "\\'"}

CTRL+O/CTRL+I (forward / back)

• partial fix: add this to your user keybindings (this only works between files, not within a file)

    [
         { "keys": ["ctrl+o"], "command": "next_view_in_stack" },
         { "keys": ["ctrl+i"], "command": "prev_view_in_stack" }
    ]
