I know this is basic, but for the life of me I can not remember how to hide/disable a specific feature point within a point layer. This seems like it should be a 2-3 click solution, but working with Arcmap I should always know better. One would think ESRI could simply make a right-click/hide point (polygon, or line), then have a "show all points in layer option" to bring it back. Thanks for the help!
first method : Select the feature that you want to hide, right click on the feature class--> selection > switch selection), right click on the feature class -->selection > create layer from selected features. Remove (or uncheck to make invisible) to old layer.
second method (needs information in the attribute table) : create a symbology with categories > unique values, remove the classes that you don't want to see and uncheck "all other values"
third method (also need information in attribute table) : right click on the layer > properties > definition queries, then write a SQL query to exclude your points.
fourth method (doesn't always work): go to the selection menu > selection option. Set the selection color identical to your background. The point "disappear" when you select them (unfortunately, with a transparent color the "normal" symbol is still visible, so this only work if your background is homogeneous)
