How to disable the left ctrl key

i have a terrible propensity to miss the left shift key and hit the ctrl key. writer includes so many macros which do weird things & when undetected i have to go back to a prior, file & hope i can remember all changes made since the next to last save. someone suggested i remove the key or heat a pin & burn it thru said key to prevent it’s depression. an audible sound like caps lock would prompt an immediate ctrl z but won’t help others who are hearing impaired. i’ve tried to train myself to only use the right shift key but in time i suspect the clumsiness will return. i fear opening the keyboard will break something. thanks for any advise. a capital challenged ken

You need to delete all shortcut keys with ctrl+any key.

Tools > Customize > Keyboard > in “Shortcut keys” scroll down until ctrl+ appears select each entry you want to delecte and click Delete at the right side…

The is no differentiation between left and right ctrl key.

As your “propensity” might also show up using some other software, and as you may want to use one or another shortcut key with the help of the right Ctrl, you should search for a way to catch the hit key even in advance of the keyboard driver processing it. I must admit, I cannot give further useful advice. If it is possible at all and how, if at all, it can be done a more technical oriented forum, if any, could help with.
