If I press the up or down arrow keys, GHC kicks in and makes it so that the last line of text comes back instead of letting me intercept the arrow key. From what I have seen, you need third-party libraries to override the default behavior, but when would a user actually want that behavior in an application instead of letting the programmer handle it? Can there be a switch (like a special LANGUAGE pragma or whatever) to enable raw input capture? Console text editing applications are greatly hindered by this automatic behavior. <details><summary>Trac metadata</summary> | Trac field | Value | | ---------------------- | -------------- | | Version | 7.8.3 | | Type | FeatureRequest | | TypeOfFailure | OtherFailure | | Priority | normal | | Resolution | Unresolved | | Component | Runtime System | | Test case | | | Differential revisions | | | BlockedBy | | | Related | | | Blocking | | | CC | simonmar | | Operating system | | | Architecture | | </details> <!-- {"blocked_by":[],"summary":"Allow default keyboard behavior to be easily overriden","status":"New","operating_system":"","component":"Runtime System","related":[],"milestone":"","resolution":"Unresolved","owner":{"tag":"Unowned"},"version":"7.8.3","keywords":["input","io","raw"],"differentials":[],"test_case":"","architecture":"","cc":["simonmar"],"type":"FeatureRequest","description":"If I press the up or down arrow keys, GHC kicks in and makes it so that the last line of text comes back instead of letting me intercept the arrow key.
