League of Legends - How to set hotkey mapping for default ctrl-click e.g. print frame rate to chat screen

You should be able to assign functions keybinds through editing the PersistedSettings.json file.

If this solution does not work for you the keybinds might be manipulated through a 3rd party program and thus cannot be solved through changing settings in League alone.

From the Riot support center:

Alternatively, there is a way to change hotkeys through the system files. Since they are account-bound and saved on our servers, you will need to perform certain steps in order to override the previous hotkeys:

• First, you’ll need to open League of Legends and log into the League Client Update.
• Afterwards, you’ll need to locate the correct folder, by default, it will be in C:\Riot Games\League of Legends\Config:

• Once there, you will need to open PersistedSettings.json and find the “Input.ini” portion of the file:

• This is where you can make changes to the keybindings; once you’ve completed the changes, make sure to save PersistedSettings.json.
• Lastly, you’ll need to join a Custom Game and exit. Once completed, your keybinding changes will be saved.

I use G + click on element to show in chat the pinged element. E.g. I press G + click on frame rate to print it on chat. I never used Ctrl, i'm used to G. The only problem is that if you want to ping something in the shop, you have to press G, then P to open the shop and than you can ping the wanted item.
