Hotkeys or SendKeys options in Zoho?

Hotkeys or SendKeys options in Zoho?

I don't know much about writing macros or VBA encoding but I would like to know a method to popup the comment box of a an active cell with a macro.
I know that I can do it pressing Shift + F2. But my colleges in the company asked me to create a button in the spreadsheet to do the thing.
I made it successfully in excel using the "SendKeys" method of VBA. 
If there is any way to create a button that pop ups the comment box and put it ready to edit it (the same as Shift + F2 combination) I will appreciate to know it.
Thanks
