The Resize action allows you controlling width and height of any window in various ways, changing all of the properties together or leaving them at their default settings. You can provide exact values in pixels or relative dimensions as a percentage of the corresponding desktop size. You can choose from among several, convenient pre-defined sizes or alternatively you can define your own settings. You can also fix the minimal/maximal size of a window to keep it within a particular range of limits.
Hint Try to use 100%x0 pre-defined size for documents containing wide tables and 0x100% pre-defined size for long documents.
