            Validate next statements step by step:

            1. In the file list there are several dirs and files (like "ski",
               "Snowboard" etc.)
            2. Select "Details" view mode.
            3. Make file list in focus (e.g. by pressing mouse button)
            4. Press key "w" several times with delay LESS than 1 second.
              Selection should be changed across files started with letter "w"
              (without case sensitive).
            5. Press key "w" several times with delay MORE than 1 second.
              Selection should be changed across files started with letter "w"
              (without case sensitive).
            6. Type "winnt" (with delay less than 1 second between letters) -
               directory "winnt" should be selected.
            7. Change conditions:
              - Move column "Name" to the second position
              - Change sort mode by clicking column "Size"
            8. Repeat items 4-6

            If above is true press PASS else FAIL
