Re: Editing Sinhala and Similar Scripts

The Backspace key has never been considered an "Undo" key. Some OSes or keyboard provide an Undo key or an equivalent shortcut like CTRL+Z (but even in this case the editor may want to undo in one operation multiple successive insertions). In the ti,e of typewriters; backspaces meant going back one

Re: Editing Sinhala and Similar Scripts

There is also a distinction between editing an existing document that you opened as distinct from writing a document, going back to a certain point in document and editing that section within the same editing session. In the first case their is no history, in the second case their may be history t

Re: Editing Sinhala and Similar Scripts

Perhaps it might be useful to be able to distinguish between an "editing mode" and a "composition mode": editing mode would be active when a document is first loaded into the editor, when the editor has no keystroke history to consult, and in this mode the backspace key would merely r

RE: Editing Sinhala and Similar Scripts

If you click into the existing text in this email and backspace, what keystroke will you expect to be "erased"? Your system has no way of knowing what keystroke might have been involved in creating the text. What is _can_ make sense to talk about is to say that a user expects execution of a par

RE: Editing Sinhala and Similar Scripts

And I think you need to distinguish between *proximate* behavior in an editor and editing behavior in general. Once a user enters editing mode, the expectation that we (the software community writing text editors) have built, in interaction with users, is that within reason, something that you ha

LOL, that's why, if the input framework allows it, its easier to support both approachable to backspace or at least an option to choose one or the other. ; ) Andrew On 19/03/2014 11:37 PM, "Doug Ewell" wrote: > Richard Wordingham wrote: > > Typing is a nightmare. >>> >> >> When you backspa
