See this On SO. You have to use nested if statement to check for ctrl then alt then 1 key before to proceed with the clipboard and writing its content to a file.
Or you can use a different approach. Write the simple script to get the clipboard contend and add/write it to a file. Just that. And when you need it run it with a key combination by your choice. It will do its job then will exit until the next time you need it.
