This is a python script that creates a clipboard that stores multiple messages at once. You can use a batch file in Windows to automate this process. This will be useful if you do a lot of repetitive typing when responding to emails for example.
This uses the 3rd party pyperclip module which gives us access to control over the clipboard. You can install this entering 'pip install --user pyperclip' into your terminal. You can go in and modify the TEXT dictionary in mclip.py to include your own phrases. Each key is used as a keyphrase for quick access. You can run this file using 'python \path-name\mclip.py [keyphrase]' in the terminal OR by replacing <path-name> in the batch file (mclip.bat) with your local path name, and saving the batch file to your C:\Users\<name> folder. You can then either run the batch file via the file explorer or press WIN+R, enter in 'mclip [keyphrase]' and it will copy whichever message is associated with the given keyphrase. Not on Windows?
