Function button
Sometimes some movements are triggered even if you did not mean it.
Since that version, 8Vim has a new button on the sidebar called fn.
If this button/feature is disabled some actions/movements marked as function won't be triggered. By default, this feature is on.
Disabled icon on the sidebar

Enabled icon on the sidebar
