With this Userscript for TamperMonkey (https://chrome.google.com/webstore/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo) you can use J and K keyboard keys to skip through the LinkedIn feed items. Saves you alot of scrolling. On Facebook and a lot of other sites this behavior is added for feed kind of pages.
When Tampermonkey is added as an extension you can visit https://github.com/derkmdt/Userscript-LinkedIn-KeyboardShortCuts/raw/master/LinkedIn-KeyboardShortCuts.user.js . Tampermonkey wil recognize this as a script to include. You then can click the "add button".
