As a software engineer I work often in IDE. Due to muscle memory I tend to solve problems by pressing alt-enter. It woud be awesome that libreoffice would support this shortcut. So if there is a detected problem with my text (for example a spelling error), that I can press alt-enter and that it provides me a context menu where I have a selection of possible fixes.
Please edit into your question all relevant information (OS, LibO version, etc.) - in this case, OS, as I doubt that there is an “inner” LibO solution – although, there might be via macro.
A LO-writer is not development/programming software, but text editing software is development of special functions focused on how text editing has evolved the last decades. For example there is ‘auto correct’, a function that can be used to correct typo’s but also for completing long and difficult information that is used regularly. My spouse makes her own auto correct table with the names of book characters, while translating she only need to type ws for Will Smith.
contnd> these functions can display a wavy line under words that are suspected to be misspelling or wrong grammar while you type, saving you a [Alt]+[Enter] for a pop-up that hast to be popped away again.
And then there are the uncountable occasions where language is not logic enough for auto correct.
Ever bought some meet at the butcher? Or did you meat that person at the party? 
These kind of errors you can get in a lot of languages, where our brain 'get it right away but the PC not.
