When using the standard Windows keyboard shortcut to close a window/application (Alt-F4), Libre Office Calc and Writer do not close. This may also happen with the other Libre Office apps, but I do not use them. When hitting the Alt-F4 combo, Calc and Writer just do what they are configured to do when someone hits F4 (i.e. for calc, alternates between relative and absolute references, and for writer, shows the data sources pane). Some Linux distros use Alt-F4 as a close window shortcut as well, but I haven't tried the 5.1+ on them to see if it suffers from the same problem. This shortcut is used by people who do not use the mouse as much (such as visually impaired users) and should be available. Thank you!
Can not confirm. The Alt+F4 performs the .uno:Quit as expected. On Windows 10 Pro 64-bit en-US with Version: 5.2.0.1 (x64) Build ID: fcbcb4963bda8633ba72bd2108ca1e802aad557d CPU Threads: 8; OS Version: Windows 6.19; UI Render: GL; Locale: en-US (en_US) The .uno:Quit (F4_MOD2)|(Q_MOD1), .uno:CloseDoc (F4_MOD1), and .uno:CloseWin (W_MOD1) function as intended and the short-cut assignments are intact in source. And for specific locations where document control might take precedent over the frame (I could not find a specific case), entering an F10 key would move focus to where Alt+F4, Ctrl+F4, Ctrl+W, or Ctrl+Q function as desired. =-ref-= Shortcuts - Accelerators http://opengrok.libreoffice.org/xref/core/officecfg/registry/data/org/openoffice/Office/Accelerators.xcu#7178 http://opengrok.libreoffice.org/xref/core/vcl/source/window/keycod.cxx#37
I've had this issue for a while as well. I only use Calc and Writer and it's only an issue with Calc for me. Also, most importantly, this issue only applies to the right alt key. Left Alt+F4 works as expected for me.
