If the cell contains a lot of data, it's slow to change focus to/from the cell. For example if I run a cell with the following, once it's completed it takes around 2 seconds to focus in or out of the cell (tested on Chrome and Firefox on a Macbook Air). This is especially frustrating when I'm trying to quickly navigate around the notebook with \"J\" and \"K\".\r\n\r\n```\r\n%%bash\r\ncurl http://en.openei.org/doe-opendata/dataset/3e440383-a146-49b5-978a-e699334d2e1f/resource/3f00482e-8ea0-4b48-8243-a212b6322e74/download/iouzipcodes2011.csv\r\n```\r\n\r\nA related issue, if I try and display an equivalently large HTML table (i.e. the display output from a pandas dataframe), the whole browser window seizes up. Maybe this is a limitation of using HTML to display tables, however I think we need to have a way to browse/view large tabular datasets to avoid the need for an external depenency on something like Excel.\r\n\r\n**EDIT** Just realized if I toggle the output of the cell, there is no problem navigating across the cell, so maybe it's not such a big problem."},"comment":{"url":"https://api.github.com/repos/jupyter/notebook/issues/comments/275030994","html_url":"https://github.com/jupyter/notebook/issues/2049#issuecomment-275030994","issue_url":"https://api.github.com/repos/jupyter/notebook/issues/2049","id":275030994,"user":{"login":"gnestor","id":512354,"avatar_url":"https://avatars.githubusercontent.com/u/512354?v=3","gravatar_id":"","url":"https://api.github.com/users/gnestor","html_url":"https://github.com/gnestor","followers_url":"https://api.github.com/users/gnestor/followers","following_url":"https://api.github.com/users/gnestor/following{/other_user}","gists_url":"https://api.github.com/users/gnestor/gists{/gist_id}","starred_url":"https://api.github.com/users/gnestor/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/gnestor/subscriptions","organizations_url":"https://api.github.com/users/gnestor/orgs","repos_url":"https://api.github.com/users/gnestor/repos","events_url":"https://api.github.com/users/gnestor/events{/privacy}","received_events_url":"https://api.github.com/users/gnestor/received_events","type":"User","site_admin":false},"created_at":"2017-01-25T06:37:28Z","updated_at":"2017-01-25T06:37:28Z","body":"I can't reproduce.
