# LOGICAL ZOOM MODE OCCURRENCE DESCRIPTION NOTES EXAMPLES WARNINGS BUGS ## OCCURRENCE
### ARB_NT and ARB_PARSIMONY: <LZoom> button in the left column ### F5 on the keyboard
## DESCRIPTION
### The 'LOGICAL ZOOM MODE' allows you to display subtrees within the tree display area of the 'ARB_NT' window. ### Click on the <LZoom> button of the 'ARB_NT' window or press the 'F5' key on the keyboard to activate the 'LOGICAL ZOOM MODE'. In the latter case, the cursor has to be placed within the tree display area. ### Display a subtree: Move the cursor to that internal node of the displayed tree (section) which defines the subtree and click on the left mouse button. The subtree-defining node is that located closest to the indicated root (open square) of the whole tree which directly or indirectly connects all branches of the subtree.
## NOTES
### To reset the display to show the whole tree either choose the 'Logical Zoom' item from the 'Tree/Reset zoom' menu or left-click somewhere outside the tree or press the key '0' (zero) in the tree display.
