Väldigt svårt att svara på. Du råkar inte ha en liveversion för allmän beskådning?

Nej inte än, men jag har rarat de aktuella filerna så kan du se.

Testa detta:
```
if (ord == 9) {
editor_insertHTML(objname, " ");
editEvent.cancelBubble = true;
editEvent.returnValue = false;
return;
}
```
Det lustiga är att det läggs till två gånger så många mellanslag som anges; i ovanstående fall blir det alltså fyra.

Tyvärr, ingen skillnad.

För mig fungerar det. editor_event() ser ut så här:
```
function editor_event(objname,runDelay) {
var config = document.all[objname].config;
var editor_obj = document.all["_" +objname+ "_editor"]; // html editor object
if (runDelay == null) { runDelay = 0; }
var editdoc;
var editEvent = editor_obj.contentWindow ? editor_obj.contentWindow.event : event;
// catch keypress events
if (editEvent && editEvent.keyCode) {
var ord = editEvent.keyCode; // ascii order of key pressed
var ctrlKey = editEvent.ctrlKey;
var altKey = editEvent.altKey;
var shiftKey = editEvent.shiftKey;
if (ord == 16) { return; } // ignore shift key by itself
if (ord == 17) { return; } // ignore ctrl key by itself
if (ord == 18) { return; } // ignore alt key by itself
if (ord == 9) {
editor_insertHTML(objname, " ");
editEvent.cancelBubble = true;
editEvent.returnValue = false;
return;
}
// cancel ENTER key and insert
instead
//if (ord == 13 && editEvent.type == 'keypress') {
// editEvent.returnValue = false;
// editor_insertHTML(objname, "
");
// return;
//}
if (ctrlKey && (ord == 122 || ord == 90)) { // catch ctrl-z (UNDO)
// TODO: Add our own undo/redo functionality
// editEvent.cancelBubble = true;
return;
}
if ((ctrlKey && (ord == 121 || ord == 89)) ||
ctrlKey && shiftKey && (ord == 122 || ord == 90)) { // catch ctrl-y, ctrl-shift-z (REDO)
// TODO: Add our own undo/redo functionality
return;
}
}
// setup timer for delayed updates (some events take time to complete)
if (runDelay > 0) { return setTimeout(function(){ editor_event(objname); }, runDelay); }
// don't execute more than 3 times a second (eg: too soon after last execution)
if (this.tooSoon == 1 && runDelay >= 0) { this.queue = 1; return; } // queue all but urgent events
this.tooSoon = 1;
setTimeout(function(){
this.tooSoon = 0;
if (this.queue) { editor_event(objname,-1); };
this.queue = 0;
}, 333); // 1/3 second
editor_updateOutput(objname);
editor_updateToolbar(objname);
}
```

Anledningen till att det läggs dubbelt så många mellanslag som angivits, är förstås att flera onkey*dir*\-händelser avfyras. Den slutliga koden ser därför ut så här:
```
function editor_event(objname,runDelay) {
var config = document.all[objname].config;
var editor_obj = document.all["_" +objname+ "_editor"]; // html editor object
if (runDelay == null) { runDelay = 0; }
var editdoc;
var editEvent = editor_obj.contentWindow ? editor_obj.contentWindow.event : event;
// catch keypress events
if (editEvent && editEvent.keyCode) {
var ord = editEvent.keyCode; // ascii order of key pressed
var ctrlKey = editEvent.ctrlKey;
var altKey = editEvent.altKey;
var shiftKey = editEvent.shiftKey;
if (ord == 16) { return; } // ignore shift key by itself
if (ord == 17) { return; } // ignore ctrl key by itself
if (ord == 18) { return; } // ignore alt key by itself
if (ord == 9 && editEvent.type.toLowerCase() == "keydown") {
editor_insertHTML(objname, " ");
editEvent.cancelBubble = true;
editEvent.returnValue = false;
return;
}
// cancel ENTER key and insert
instead
//if (ord == 13 && editEvent.type == 'keypress') {
// editEvent.returnValue = false;
// editor_insertHTML(objname, "
");
// return;
//}
if (ctrlKey && (ord == 122 || ord == 90)) { // catch ctrl-z (UNDO)
// TODO: Add our own undo/redo functionality
// editEvent.cancelBubble = true;
return;
}
if ((ctrlKey && (ord == 121 || ord == 89)) ||
ctrlKey && shiftKey && (ord == 122 || ord == 90)) { // catch ctrl-y, ctrl-shift-z (REDO)
// TODO: Add our own undo/redo functionality
return;
}
}
// setup timer for delayed updates (some events take time to complete)
if (runDelay > 0) { return setTimeout(function(){ editor_event(objname); }, runDelay); }
// don't execute more than 3 times a second (eg: too soon after last execution)
if (this.tooSoon == 1 && runDelay >= 0) { this.queue = 1; return; } // queue all but urgent events
this.tooSoon = 1;
setTimeout(function(){
this.tooSoon = 0;
if (this.queue) { editor_event(objname,-1); };
this.queue = 0;
}, 333); // 1/3 second
editor_updateOutput(objname);
editor_updateToolbar(objname);
}
```
