• we added Alt + O keyboard shortcut for CmdOpenFolder command. It opens a folder for browsing.
• by default SumatraPDF has Ctrl + O shortcut for CmdOpen (open a file) command. This changes the shortcut to x
• by default q closes the document. By binding it to CmdNone we can disable a built-in shortcut
• ver 3.6+:: CmdCreateAnnotHighlight takes a color argument (#00ff00 is green) and boolean openedit argument. We re-assign a to create a highlight annotation with green color (different from default yellow) and to open annotations edit window (openedit boolean argument)

Format of Key section: #

• just a key (like a, Z, 5) i.e. letters a to z, A to Z, and numbers 0 to 9
• modifiers + key. Modifiers are: Shift, Alt, Ctrl e.g. Alt + F1, Ctrl + Shift + Y
• there are some special keys (e.g. Alt + F3)
  • F1 - F24
  • numpad0 - numpad9 : 0 to 9 but on a numerical keyboard
  • Delete, Backspace, Insert, Home, End, Escape
  • Left, Right, Up, Down for arrow keys
  • full list of special keys
• without modifiers, case do matter i.e. a and A are different
• with modifiers, use Shift to select upper-case i.e. Alt + a is the same as Alt + A , use Alt + Shift + A to select the upper-case A
