Studly Next

Summary: Jump to the next intra-word. Works like a finer-grained Option-Rightarrow.
Requires: BBEdit 8 (similar functionality built-into BBEdit 8.5)
Suggested Key Binding: Control-Rightarrow
Last Modified: 2010-11-27


This script brings CodeWarrior’s Control-Rightarrow functionality to BBEdit. It lets you jump between the parts of words with with inner caps (a.k.a. studly caps or camel case). This is very useful for programmers who follow the Apple or Java naming conventions.

This script works like a finer-grained Option-Rightarrow. Instead of moving to the next word, it moves to the next capitalized part of a word. For instance, the underscored positions in: _set_Script_Error_Number_.
