Here is a simple way to just add a 'check mark' to any cell in a specified column just by double clicking the cell. This was created in Excel for PC, but Excel 2011 supports macros/event handlers created in Excel.
The following example uses column 'A' (1) as the column to return the check mark in. If your column is not 'A', change the '1' to the number representing your column, i.e. A = 1, Z = 26.
Then, copy the following code, modified if needed, to the clipboard:
Private Sub Workbook_SheetBeforeDoubleClick(ByVal Sh As Object, _
ByVal Target As Range, Cancel As Boolean)
If Target.Column = 1 Then
ActiveCell.Font.Name = "wingdings 2"
ActiveCell.Font.Size = 12
ActiveCell.Font.Bold = True
ActiveCell.Value = "P"
ActiveCell.HorizontalAlignment = xlCenter
End If
End Sub
Select the sheet you wish to use this in and right click the sheet tab.
Select 'View Code'
Paste the event handler into the white editing area to the right.
Close the VBE and return to the worksheet.
Double click any cell in your specified column and the check mark will be entered.
Note: the accessing of the VBE in Excel 2011 for Mac may be different than indicated above. Not sure, I don't have a Mac.
