Lucide 1.3.1 available

April 21, 2010 by, Mensys BV and Serenity Systems International are pleased to announce the availability of Lucide 1.3.1.

The most important changes since version 1.2.1 are:

  • Both the full screen and presentation modes can now be closed by Alt-F4.
  • The full screen or presentation mode is properly saved when exiting Lucide and restored at startup.
  • Pressing the "+/=" key moves to the next page (previously, it was necessary to hold Shift to make it work in many keyboard layouts).
  • Unified keyboard navigation in all modes.
  • Auto-scroll the index window to make sure the current page is always visible.
  • Made Enter submit the edited text in multi-line entry fields.
  • Fixed scrolling the document with RMB and enabled it in presentation mode
