Here is a list of other changes in the new Sumatra version:

Users who prefer the keyboard can use the Command Palette using the keyboard only. You may browse the available selection of commands or type to filter available commands and options. Open the Command Palette via Menu > View > Command Palette, or by using the keyboard shortcut Ctrl-K. It may be used to open recently opened PDF documents quickly, to switch between tabs, and to invoke any of the available commands that Sumatra supports. The new Command Palette unlocks all functions of the PDF reader when it is opened. The key variable accepts single keys and key combinations, e.g., Alt-I or q. The Cmd parameter accepts any of the supported commands, e.g., CmdBookView, which you find listed here on this page.

For each, Cmd and Key variables need to be set. The Shortcuts section of the file handles custom keyboard shortcuts. Sumatra 3.4 introduces support for custom keyboard shortcuts and for the remapping of existing keyboard shortcuts this is done using the configuration file as well under Settings > Advanced Settings. Basically, what you need to do is copy the target URL of the service and replace the query with the $ parameter.
