Refresh shortcut?

Is there a keyboard shortcut key that I can use to refresh email? In other words, send and receive all? In most applications, F5 is refresh. But this does not seem to work in Emclient.

Does this not work?

Yes it does, but I’m looking for a keyboard shortcut.

I realized that the problem seems to be more that YAHOO server often takes some time to sync up, and does not always immediately sync. When I hit F5, nothing happens, but that is because of the syncing delay.

Not sure I understand why it has to be a KB shortcut. Hope your search is successful.
