Is there any shortcut to iterate through Excel's worksheet tabs?
Right click on any bottom corner left arrow keys, you will see list of all sheets and select the required sheet on the workbook.
Refer my screenshot:-
Windows:
Switch between worksheets: CtrlPgDn or CtrlPgUp
Switch between workbooks: CtrlTab or CtrlShiftTab
OS X:
Switch between worksheets:
FnCtrl↓ or FnCtrl↑ on a small keyboard
Ctrl⇞ or Ctrl⇟ on a keyboard with numpadSwitch between workbooks: CtrlTab
For mac OSX:
To switch between tabs in a worksheet: Fn + Command + up/down!
