By default, MPS moves the caret to the end of the current word.

When you move the caret to the previous word, the caret is placed in the beginning of the current word. You can configure the position of the caret when you use these actions.
In the Settings/Preferences dialog Ctrl+Alt+S, go to Editor | General. In the Caret Movement section, use the When moving by words and Upon line break options to configure the caret's behavior.
To move the caret forward to the next paragraph or backward to the previous one, press Ctrl+Shift+A and search for the Move Caret Forward a Paragraph or Move Caret Backward a Paragraph action.

You can also select a text and then move the caret forward or backward to a paragraph. Press Ctrl+Shift+A and search for the Move Caret Forward a Paragraph with Selection or Move Caret Backward a Paragraph with Selection action.

If you need, you can assign shortcuts to these actions. Refer to Configuring keyboard shortcuts for details.
