Holding down a keyboard shortcut, such as CTRL+Z, results in extreme CPU usage and Komodo IDE freezing up until well after I let go of the keys.\r\n\r\nPreviously I would hold down CTRL+Z to undo a series of changes, watching the changes unfold, letting go of the keys when reaching the change I was looking for. This is no  longer possible and  I have to repeatedly press CTRL+Z to undo a single change at a time.\r\n\r\nThe problem does not seem to be related to any specific command as I get the same issue when holding CTRL+A or a number of other keyboard shortcuts. The problem persists when restarting in Safe-Mode.\r\n\r\nTo reproduce:\r\n1. Open new file\r\n2. Hold CTRL+Z for a few seconds\r\n3. Watch CPU usage rise and Komodo  IDE freeze\r\n\r\nVersion info:\r\nKomodo IDE, version 9.3.2, build 88191, platform linux-x86_64"},"comment":{"url":"https://api.github.com/repos/Komodo/KomodoEdit/issues/comments/177120225","html_url":"https://github.com/Komodo/KomodoEdit/issues/1026#issuecomment-177120225","issue_url":"https://api.github.com/repos/Komodo/KomodoEdit/issues/1026","id":177120225,"user":{"login":"Defman21","id":7100645,"avatar_url":"https://avatars.githubusercontent.com/u/7100645?v=3","gravatar_id":"","url":"https://api.github.com/users/Defman21","html_url":"https://github.com/Defman21","followers_url":"https://api.github.com/users/Defman21/followers","following_url":"https://api.github.com/users/Defman21/following{/other_user}","gists_url":"https://api.github.com/users/Defman21/gists{/gist_id}","starred_url":"https://api.github.com/users/Defman21/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Defman21/subscriptions","organizations_url":"https://api.github.com/users/Defman21/orgs","repos_url":"https://api.github.com/users/Defman21/repos","events_url":"https://api.github.com/users/Defman21/events{/privacy}","received_events_url":"https://api.github.com/users/Defman21/received_events","type":"User","site_admin":false},"created_at":"2016-01-30T09:20:43Z","updated_at":"2016-01-30T09:20:43Z","body":"I'm able to reproduce it. Create lipsum of 100 words and start deleting it by a character - for me Komodo starts lagging a lot and CPU usage jumps to 100% (I've AMD FX8350 4.0GHz). Then hold <kbd>Ctrl+Z</kbd>. Komodo is lagging when undoing the text and again CPU usage jumps to 100-120%. This happens mostly when I delete long strings (about 30+ characters in them). If I just type 5 characters and do something with them (remove or add something) and then hold <kbd>Ctrl+Z</kbd> - Komodo deals with it very good and fast."}}
