Moving around in the text in KatePart is similar to most graphical text editors. You move the cursor using the arrow keys and the PgUp, PgDn, Home and End keys in combination with the Ctrl and Shift modifiers. The Shift key is always used to generate a selection, while the Ctrl key has different effects on different keys:
For the Up and Down keys it means scroll rather than move the cursor.
For the Left and Right keys it means skip words rather than characters.
For the PgUp and PgDn keys it means move to the visible edge of the view rather than browse.
For the Home and End keys it means move to the beginning or end of the document rather than the beginning or end of the line.
KatePart also provides you with a way to quickly jump to a matching brace or parenthesis: place the cursor on the inside of a parenthesis or brace character, and press Ctrl+6 to jump to the matching parenthesis or brace.
In addition you can use bookmarks to quickly jump to positions that you define on your own.
