* use mouse wheel in the main editor,
* go to the menu *View* -> *Previous Line* or *View* -> *Next Line,*
* click on the line (only works for active track's lines) in the *fillbar* as explained [*here*](/karedi/user-interface/middle-components/song-fillbar.md#adjusting-the-visible-area-to-some-line)*.*

## Moving around

To move visible area without changing its size you can:

Use `ctrl + shift + mouse wheel scroll` or `ctrl + horizontal mouse wheel scroll` to zoom in or zoom out horizontally.

Use `alt + shift + mouse wheel scroll` or `ctrl + alt + horizontal mouse wheel scroll` to zoom in or zoom out vertically.

Use *fillbar* as explained [*here*](/karedi/user-interface/middle-components/song-fillbar.md#increasing-decreasing-the-visible-area)*.*
