Total Commander

Currently in TC 11.00b4 the wincmd.ini parameter CtrlArrow takes two values 0 or 1.

I suggest that CtrlArrow could also be used to set user-defined set of separators - like:
CtrlArrow=\/(),.;=''^+-%&!_[ ]{}|:@

Equal to the parameter:
CompareResyncSeparators=., ;:_+-*/\?!()[]{}"'@

CtrlArrow=0 should still disable the function, and CtrlArrow=1 should enable it with the predefined separators.

Great idea!

Another idea: For CamelCase in filenames (e.g., "ThisIsAQuiteLongCamelCaseFilename.txt") it would be great if TC would detect the camel case and Ctrl+Arrow would stop at the end/begin of each word.

How about
CtrlArrowSeparators = As list of chars as described by *petermad
CtrlArrow = 0 + 1 + 2
Where 1 still activates the internal Ctrl+Arrow key movement method and 2 activates CamelCase detection in addition.

Support++ if it is feasible for CamelCase (maybe just for English characters)

Support for character enumeration and caret navigation relative to uppercase letters (no language restrictions).

Now that the function has been disabled by default because of the lacking windows functions to set the cursor, I see little incentive to work on this.

Hmm, It works reasonably well in TC 11.00b4 - but I am using a Western locale, if seems that there are ploblems with other locales.

For me it also works quite well in TC11.00b4 -- I would highly appreciate the feature extension...

I'd love to have this; from all the other IDEs, I often find myself doing [ctrl]+[left]/[right]; similarly, it would be awesome for [ctrl]+[backspace] to remove all content in text inputs.
