Answer 1

Hello @Smrithi Surendran ,
Welcome to Microsoft Q&A!

It is recommended that you set the enum constants to the power of 2.
You can see official document code sample it also be power of 2.

In your example the values look like this

A = 0 0000
B = 1 0001
C = 2 0010
D = 3 0011

Key = Keys.B | Keys.C;
B | C = 0011 which is 3 or D

If you choose powers of 2, you will get

A = 1 = 2^0 0001
B = 2 = 2^1 0010
C = 4 = 2^2 0100
D = 8 = 2^3 1000

You can refer to this question operator with enum values in C#

Thank you.

Answer 2

It is recommended that you define the keys according to the power of 2.
For example, if you have a shortcut key is D+G, if it means screenshot,
then the definition of the screenshot key is Key= Keys.D | Keys.G
Screenshot = Keys.D | Keys.G =72 = 0100 1000

A = 1 = 2^0 0000 0001
B = 2 = 2^1 0000 0010
C = 4 = 2^2 0000 0100
D = 8 = 2^3 0000 1000
E = 16 = 2^4 0001 0000
F = 32 = 2^5 0010 0000
G = 64 = 2^6 0100 0000
Screenshot=72
H =128 = 2^7 1000 0000

Similar to the definition in the official code sample

// The example displays the following output:  
//       All possible combinations of values without FlagsAttribute:  
//         0 - None  
//         1 - Black  
//         2 - Red  
//         3 - 3  
//         4 - Green  
//         5 - 5  
//         6 - 6  
//         7 - 7  
//         8 - Blue  
//         9 - 9  
//        10 - 10  
//        11 - 11  
//        12 - 12  
//        13 - 13  
//        14 - 14  
//        15 - 15  
//        16 - 16  
//  
//       All possible combinations of values with FlagsAttribute:  
//         0 - None  
//         1 - Black  
//         2 - Red  
//         3 - Black, Red  
//         4 - Green  
//         5 - Black, Green  
//         6 - Red, Green  
//         7 - Black, Red, Green  
//         8 - Blue  
//         9 - Black, Blue  
//        10 - Red, Blue  
//        11 - Black, Red, Blue  
//        12 - Green, Blue  
//        13 - Black, Green, Blue  
//        14 - Red, Green, Blue  
//        15 - Black, Red, Green, Blue
