The simplest move action is moving your speed. If you take this kind of move action during your turn, you can’t also take a 5-foot step.
Many nonstandard modes of movement are covered under this category, including climbing (up to one-quarter of your speed) and swimming (up to one-quarter of your speed).
Accelerated Climbing: You can climb one-half your speed as a move action by accepting a -5 penalty on your Climb check.
Crawling: You can crawl 5 feet as a move action. Crawling incurs attacks of opportunity from any attackers who threaten you at any point of your crawl.
