The desktop client for Mac has a keyboard shortcut for inserting a table (Cmd + Shift + L). The Windows client has never had a shortcut for this, to my knowledge. I use tables all the time, and find it very cumbersome and time consuming to press Alt, O, T, selecting number of rows and columns in the dialog and then press Enter. I regularly mess up something, like pressing the combination of keys too fast, etc. The overall quality of the desktop client for Windows seems to have improved over the last 6 months or so. I am thankful for that.
