How can I jump 2 words at a time throughout Windows?

AutoHotkey will do exactly that. Or you can tailor the shortcut keys to be context specific and only trigger when certain programs are active.

#Persistent

#IfWinActive      ; Every window. Change this line to tailor specificity
^!Left::SendInput, ^{Left 2}
^!Right::SendInput, ^{Right 2}
^!Backspace::SendInput, {Backspace 2}           ; delete two characters at a time
^!Backspace::SendInput, +^{Left}{Backspace}     ; delete a word at a time
^!Backspace::SendInput, +^{Left 2}{Backspace}   ; delete two words at a time

Pick only one of the three definitions for Ctrl + Alt + Backspace obviously.

Hotkey modifiers are in the AutoHotkey help file, but for quick reference, ^ is Control, ! is Alt, + is Shift and # is the Windows button.

If you need to make a multi-line macro with sleep statements or something, start on the next line after the hotkey definition and end the macro with a Return statement.

^!Left::
    SendInput, ^{Left 2}
    Sleep 200                   ; Sleeping 10 to 200ms can help for 
                                ; reliability in multi-key-press functions,
                                ; depending on what you're doing
Return
