Currently I have MailTab for Gmail (Pro version linked, there is also an ad-supported free version) which has a custom keyboard shortcut option available. There also is a flavor for Outlook by the same developer.
To take it a step further, Using BetterTouchTool (BTT), one can set a specific gesture on the touchpad to invoke a keyboard shortcut. BTT also allows for additional actions to take place, such as "Send shortcut to specific app", after performing a gesture (or even a keyboard shortcut). So the flow is:
- Double tap lower right corner
- BTT invokes shortcut for MailTab (Default is
ctrl + g)
- BTT sends the shortcut
c to MailTab
c is the shortcut for compose in the web view for GMail. For more keyboard shortcuts for gmail type
? while at your inbox for a comprehensive list.
All this happens when I double tap the lower right corner. I tried to eliminate the need for sending a shortcut to bring the inbox into view by calling on the app itself via BTT, but it doesn't want to play nice.
