When you create a big matrix (more than 15 columns and/or more than 20 rows), only part of the matrix is displayed at a time. This is done to spare the loading time and server resources.

**Map navigation** Matrix map will
appear in the right top corner of the matrix screen.The green
highlighted area is the part of the matrix that is currently
displayed. Click on any cell on the matrix map to move to that part
of the matrix.

**Arrow navigation**
Up/down/right/left arrows will appear around the matrix if there
are more cells in the corresponding direction. Click on the arrow
to move one block up/down/right/left. By block we mean the current
number of visible columns/rows. For example, if you have a matrix
with 40 rows and rows 1-20 are currently displayed, the next block
down will be rows from 20 to 40.
