For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Copy and paste / cut and paste and other vi techniques

* If you want to duplicate a line, you can yank it with Y into the default yank buffer, then move your cursor and push it out with p or P to push it after or before the current line.

* To move a line, delete it with dd which puts it into the yank buffer, then push it with p or P.

* The number of lines to be yanked or deleted can by typed in before you Y or dd and vi will yank or delete that number of lines.

* If you want to remember whereabouts in your text you are so that you can come back later, you can drop a marker - ma will set a marker "a" and you can return to that marked line later using 'a - that's a quote followed by the marker name.

* The %command will jump the cursor to a matching bracket

* J joins 2 lines together

* and :e![cr] says "I made a right mess of that - abandon my changes and re-read the input file

Leah:Very useful, thanks!

With setting the markers, it sounds as though one could set multiple markers? Can it be set with more than character, like -mstuff and 'stuff?

graham:Markers are single characters, but you can use letters (capital and lower case) and most special characters too which should (!) be plenty. The problem with multiple characters is that you woul;d need to have a deimited when you set them up and re-use them
