I think, with text blocks you mean Templates. No, it is not possible to define more than 50 templates. Modifying the file while UltraEdit is running also does not work. The content of the template file is loaded only once at start of UltraEdit.

However, you can use macros for expanding the number of predefined text strings. A macro can also have only the job to insert text and nothing more. You can define also individual hot keys for the "macros". It's also possible to call a template within a macro to use the special time/date/path and file name formating features of templates.

Collect all "template" macros in a single macro file and specify this macro file for autoload. Use the Macro List view to execute one of this macros for inserting a text.

Finally you should also read in the help of UltraEdit and the forum about the Auto Completion feature of UltraEdit. Maybe this could be also helpful for you.

Well, you can write a macro which changes the template directory specification in uedit32.ini if the INI is always in the same directory. But this hack in the INI does not have any effect until you restart UltraEdit.

Maybe instead of templates you could use tags.

Do you know the tag feature of UltraEdit/UEStudio?

Tags are similar to templates. They are not so powerful than templates. But they have an equivalent for a single usage of [$replace$] - enclose a selected text with a start and end tag (=text) or simply insert the text (tags) if nothing is selected. The cursor is also automatically placed between a start and end tag when inserting a tag. Multi-line tags and tags with tabs are also possible.

Disadvantages of tags in comparison to templates:

1. Tags cannot be assigned to hot keys.
2. There are no special codes to insert a date/time or a file name in a customizable way like it is possible with templates.
3. The cursor is automatically placed either between start and end tag or after the start tag if there is no end tag. It's not possible to specify where exactly the cursor should be after inserting the text.
4. The tags are not available via a menu, only via the Tag List window.
5. No equivalent for [$REPLACE$] code of templates.
6. Tags from a taglist file cannot be used in macros like templates.

Advantages of tags in comparison to templates:

1. No limit (as far as I know).
2. Can be grouped for different languages, projects or users.
3. You can have as many taglist files as you want with names you like and can easily change it via the context menu of the tag list window.
4. A taglist file which holds the tags is a normal text file and not a binary file like the storage file for templates. So they can be easily shared, modified or translated without UltraEdit and its special dialogs for editing tags or templates.
5. Macros can be used to easily modify the content of a taglist file. However, the modifications on an already loaded taglist file by a macro will be detected by UE only when restarting UE or reload the file via the Modify Tags dialog.

For more about templates and tags see Alternative to this BBS macro where Paolo and I are currently creating a taglist file for BBCode and the infos I have posted in my first post at this thread. See also the pages linked there.

See my post at taglist file how to create multi-line tags.
