Allows vertices or bones to be selected by matching an expression using a simple query syntax.

An expression takes this form: <axis|datatype> <operator> <value>. The axis or datatype determines what type of data is to be selected. The operator determines how the value is interpreted. The value is a number used to discriminate between elements of the specified type.

Valid axis values are "x", "y", and "z" if referring to vertex position, and "bx", "by", and "bz" if referring to bone position.

Valid datatype values are "v" to refer to vertex index; "f" to refer to face index; "p" to refer to partition ID; "b" to refer to bone index; and "w" to refer to bone weight.

Valid operators are "==" for equality, "!=" for inequality, "<" for less than, "<=" for less than or equal, ">" for greater than, and ">=" for greater than or equal.

Examples:
• Select all vertices with an x coordinate greater than zero: "x > 0"
• Select the face at index 4: "f == 4"
• Select all bone endpoints with a z coordinate less than or equal to zero: "bz <= 0"
• Select all vertices in partitions other than 1: "p != 1"

Press enter to evaluate the expression and perform selection of the specified data. If Shift is held while pressing enter, any matched data will be added to the existing selection rather than replacing it. If Ctrl is held, matches will be subtracted from the current selection. If both Ctrl and Shift are held, matches will be toggled.
