How can i define a shortcut like "c" for "create", "d" for "delete" or "n" for "new" by select menus in shell scripts?

Code:

```
#!/bin/bash

PS3="Enter an option: "

select option in create delete new quit
do
    echo "Selected option was: $option"

if [ "$option" == "create" ]

then

read -r -p 'Create new partition: Please define a name of the partition: ' new_partition

read -r -p 'Define Size: Please define a size of the partition: ' partition_size

break

fi

if [ "$option" == "delete" ]

then

read -r -p 'Delete partition: Please define a name of the partition: ' delete_partition

break

fi

if [ "$option" == "new" ]

then

read -r -p 'Reset memory usage: Please define a name of the partition: ' reset_partition

break

fi

if [ "$option" == "quit" ]

then

break

fi

done

```
