Just to extend what mark said the reason is each time you change a tiddler. the change gets propagated throughout the wiki,
at least where it is relevant. This is how everything in TiddlyWiki is always up to date, your changes are automatically updated.
Add a new item and it appears in a list immediately etc...
Editing the current tiddler would immediately update the display of itself, to address this the edit mode mechanism uses a draft
tiddler has[draft.of]] detects this in filters. When editing you are actually editing a different tiddler which is "committed" when done.
This also allows you to cancel the edit with X and the previous unedited version is "restored".
The fact is most of us want to make forms or interactive wikis for those who do not know tiddlywikis editor. If you make one tiddler edit
another this will be fine, or use marks method, but since tiddler titles represent something we like to change we often want to do what you wanted.
Pastes work because they are equivalent to one character and then you loose focus as things update. Typing on the other hand,
You loose focus every letter.
I have built a range of workarounds but all a inside more complex solutions than a simple edit. I continue to look for a simpler way.
And would like to see a feature to address this built into the core. It is but a simple technical issue to resolve but a complex user issue.
I so far I have not seemed to convince others with the tech skills how important this one improvement would be.
Keep asking Questions and we will help.
