 ====== Workspace Functions ======
-This page contains a list of all functions that can be applied to the active workspace.
+Most Visual3D commands act on the active files and active subjects.This page contains a list of all functions that can be applied to the active workspace.
 ==== File Tag Exists ====
-**File_Tag_Exists(a)** - Tests the existence of a file tag "a" within the active workspace. Returns 1 if the file tag exists and 0 otherwise. This behaviour is similar to the expression [[visual3d:documentation:pipeline:expressions:signal_functions#data_exists|Data Exists]].
+**File_Tag_Exists(a)** - Tests the existence of a file tag "a" within the workspace's active files, where "a" must be specified within [[visual3d:documentation:pipeline:expressions:expression_syntax#tag_syntax|the TAG:: namespace]]. Returns 1 if the file tag exists and 0 otherwise. This behaviour is similar to the expression [[visual3d:documentation:pipeline:expressions:signal_functions#data_exists|Data Exists]].
 Example, compute “something” only if the file tag SPECIAL exists.
