Since New Twitter is available to all users worldwide we’ve covered its shortcuts also, and twitter kind enough and gave the option to use old twitter for some time till the Preview of New Twitter is over, well if you are switched to Older version of Twitter you need to switch to “New twitter” now and get used to it because Twitter is going to end its older version.
Twitter started showing warning for users using old twitter to switch to new twitter by showing message “ You’re using an older version of Twitter that won’t be around for much longer”.
And if you switch to New twitter from older one, twitter greets with “ Welcome to New Twitter, Read up on What’s New . You can still access old twitter for a limited period of time”.
P.S : I am using the older version of twitter since New Twitter availability, need to switch to New Twitter
