Keyboard Manager uses process-names (not application names) to target apps. For example, Microsoft Edge is set as "msedge" (process name), not "Microsoft Edge" (application name). To find an application's process name, open PowerShell and enter the command get-process or open Command Prompt and enter the command tasklist. This will result in a list of process names for all applications you currently have open. Below is a list of a few popular application process names.
