Description tommy27 2014-01-30 02:38:15 UTC
issue is only noticeable when you work with large auocorrect replacement lists.

1- have a large autocorrect list. If you need one take this file ( attachment 57846 [details] ) which is an italian autocorrect database and put in the "autocorr" subfolder of your user profile ( https://wiki.documentfoundation.org/UserProfile )

2- open Writer and click "Tools/Autocorrect options/Replace"

3- start typing anything fast in the "Replace" field, you'll will notice some delay between keyboard hits and text visualization

4- type anything fast in the "With" field, no delay at all

CURRENT BEHAVIOUR: typing in the "Replace" field is slower than the "With" field

DESIRED BEHAVIOUR: same typing speed.

I suppose that the slowness of the "replace" field is due to the fact that while you type the list automatically scrolls down alphabetically to insert the new entry in the proper position.

If you have few autocorrect entries you won't notice the different speed but when you deal with long lists a slight delay become recognizable.


a speed improvement has been already obtained in the past during 3.6 master development. see this committ: 

anyway I wonder if a further speed up is yet possible, since a slight annoying delay is still noticeable in current LibO and 4.3alpha

Gah! Ignore my last comment. I forgot to rename the file. I see the issue now. Confirmed. Status set to NEW. Platform set to All/All.
