You can also specify keys combined with Shift and/or Ctrl and/or Alt and/or Command. To specify a key combined with another key or keys, use the following table.
| To combine keys with | Precede the key code by |
|---|---|
| Shift | + (plus sign) |
| Ctrl | ^ (caret) |
| Alt | % (percent sign) |
| Command | * (asterisk) Only applies to Mac; may only work on Excel 2011 for Mac and not later versions. |
To assign a procedure to one of the special characters (+, ^, %, and so on), enclose the character in braces. For details, see the example.
Note
There is no way to currently detect the Command key in recent versions of Office VBA. Microsoft is aware of this and is looking into it.
Example
This example assigns InsertProc to the key sequence Ctrl+Plus Sign, and assigns SpecialPrintProc to the key sequence Shift+Ctrl+Right Arrow.
This example returns Shift+Ctrl+Right Arrow to its normal meaning.
This example disables the Shift+Ctrl+Right Arrow key sequence.

Often we look to certain symbols in Excel that are hard to locate on the keyboard. Or the opposite – we look to find the Excel character codes for certain characters. In such cases we must usually revert to using the CHAR Excel function or the CODE Excel function. Let us explore these functions and how to use them both in Excel and VBA today.
Excel Character Codes
First let us start with exploring the Excel Character codes.
The table below represent the full default encoding in Excel:
On the right side is the Excel character (CHAR) and on the left you have the numeric representation (CODE) of the character. Dl bittorrent.
Converting Characters to Codes (Excel CODE function)
The Excel CODE function allows you to easily obtain the numeric code for the provided character (1 character string).
Syntax
The syntax for the CODE function in VBA is:
Parameters
string
A single character string.

Converting Codes to Characters (Excel CHAR function)
The Excel CHAR function allows you to easily obtain the character represented by the numeric code.
Syntax
The syntax for the CHAR function in Excel is:
Parameters
