example, 'guicursor' sets the terminal cursor style if possible.
*'term'* *E529* *E530* *E531*
-The 'term' option has a fixed value, present only for script compatibility and
-intentionally not the same as any known terminal type name. It should be a
-rare case in Nvim where one needs |term-dependent-settings|.
+'term' reflects the terminal type derived from |$TERM| and other environment
+checks. For debugging only; not reliable during startup. >
+ :echo &term
+"builtin_x" means one of the |builtin-terms| was chosen, because the expected
+terminfo file was not found on the system.
*termcap*
Nvim never uses the termcap database, only |terminfo| and |builtin-terms|.
