| Custom | Custom client-determined tracking behavior. | |
| EdgeExclusive | The leading edge of the span is positive tracking (insertions push the current position towards the end) and the trailing edge is negative tracking (insertions push the current position towards the start). The span will not expand when text changes occur at the span boundaries. For example, if an EdgeExclusive Span has Start position 3, and a single character is inserted at position 3, the Span will then have Start position 4 and its length will be unchanged. | |
| EdgeInclusive | The leading edge of the span is negative tracking (insertions push the current position toward the start) and the trailing edge is positive tracking (insertions push the current position toward the end). The span will expand when text changes occur at the span boundaries. For example, if an EdgeInclusive Span has Start position 3, and a single character is inserted at position 3, the Span will then have Start position 3 and its length will be increased by one. | |
| EdgeNegative | Both edges of the span are negative tracking (insertions push the current position toward the start). | |
| EdgePositive | Both edges of the span are positive tracking (insertions push the current position toward the end). |
