           Summary: Cursor navigation should not trigger code completion
                    window
           Product: kdevelop

            Status: UNCONFIRMED
          Severity: normal

        ReportedBy: fabio gs2 com br

I am using KDevelop to code PHP projects. When I navigate through the code with the arrow keys, KDevelop has the following weird behaviors:

1. When I walk on the end of a word, it displays the Code Completion Window with symbols that begin with that word, as if I was typing that word. For example, if I walk to the end of an "if", it offers me ifx_connect(), ifx_close(), etc.

2. Whem I walk to the beginning of a line that begins with tabs or an empty line, it displays the same window, offering me class names, probably thinking I created that line, offering me classes to instantiate.

In both cases, the code completion pop-up window grabs the keyboard focus, so when I press Up and Down, I move the selection of the listbox instead of moving the cursor of the text editor. In case "2", if I want to go down, walking through a lot of empty or indented lines, I must press an Esc for every Down Arrow.

This kind of behavior gets in the way when you are waking through the code and is a real showstopper, at least for those developing PHP applications. Imagine a text editor that prevents you from using the arrow keys. :P

My humble opinion is:
The code completion window should not be triggered by cursor navigation. Instead, the window should be triggered only by typing text or by hitting Ctrl+Space.
