Seconded somewhat.
<rel-obvious-or-duh>
However, the number of capitalization conversations may be numerous, and converting bit by bit via right-click...
Right, C-Script is case-insensitive and C is not.
SDK & Diet-C: structs often capitalized
STRING, TEXT, ENTITY, etc.
I remember jumping bookmarks in SED somewhat satisfactorily,
with improvement still desired.
A number of features found in Notepad++ might be useful in varying degrees.
i.e.
1. bulk replace whole word string -> STRING, all open documents
2. go to another view (side by side comparison)
3. TextFX sort
4. HexEditor (Plugin)
5. Compare (Plugin, like WinDiff) ***
...
Probably, to a limited extent, Notepad++ can be used instead of SED for Diet-C and C-Script.
Also, in C, as ~recalled, the following may be of no use:
#DEFINE string STRING
// but check that
</last-tag>
